Profile
Youri Baas is a 23-year-old Dutch centre-back born on March 17, 2003, in Oostvoorne, Netherlands. 182cm, left-footed. At AFC Ajax since 2018 (youth), wearing #15. Contract until June 30, 2028. Career path: OVV Oostvoorne → Excelsior (2012-2018) → Ajax Youth (2018-2020) → Jong Ajax (2020-2023, 50 apps, 2G) → Ajax first team (2022-) → NEC Nijmegen (loan 2023-24, 30 apps, 3G) → Ajax (2024-). Named Ajax Talent of the Year 2024-25 and Ajax Player of the Year 2025-26. Netherlands national team — called up March 2025 vs Spain (unused substitute), 0 senior caps. Market value: €20.0M (Transfermarkt). Reported interest from Liverpool (Arne Slot).
T3 Status
0/16 T3 metrics validated. No full-match isolated footage evaluated under ESN methodology. All 16 Empire FGA T3 metrics — OBI_P, OBI_T, OBI_S, SII_A, SII_T, SII_R, DMA, CHR, MCS, SPI, CLM, CRS, OMS, DYN, CRK, SOA — are pending scout review. Recommended T3 context: Ajax 2025-26 vs PSV/Feyenoord (minimum 5 matches), Ajax vs Barcelona/Real Madrid UCL, Netherlands U21 Euro 2025 (if recovered from injury). Priority T3 focus: DMA confirmation (can 92.4% pass accuracy be verified as elite creative intelligence in isolated footage?), OBI_P validation (35 interceptions + 57 tackles — positional reading or system product?), SII_A/SII_R (physical recovery speed and muscular durability post-groin injury), CHR (0 senior caps at 23 — mental block or timing issue?).
Empire FGA Verdict
FGA 7.2 — Eredivisie CB · Ajax Player of the Year · Elite Ball-Playing Defender · Build-Up Metronome · Netherlands Prospect. The T1 data is exceptional for a 23-year-old centre-back: 92.4% pass accuracy (most passes in Eredivisie), 140 ball recoveries (most at Ajax), 35 interceptions, 57 tackles, 31 blocks, 137 clearances. But the Eredivisie LOG is 2.8 — the same confounding variable as Mika Godts. The €20M market value and Liverpool interest suggest the market believes in the translation. Cruyff / Total Football ball-playing CB first, Guardiola positional second, Bilardo defensive third. T3 assessment is critical before any €20M+ transfer recommendation. The Ajax system inflates possession stats — validation against elite pressing (UCL, PSV) is mandatory.

Cross-League Performance Projection
LOG (Level of Game) contextualizes performance across leagues of differing quality using Empire FGA's Competition_Tier_Base reference. Baas's 7.2 FGA is an estimated figure — 0/16 T3 metrics confirmed, all scores derived from Tier 1 statistical data. This projection carries high evidentiary uncertainty because the Eredivisie (LOG 2.8) is significantly below the top-5 European leagues, and Ajax's possession-dominant system inflates passing metrics. The 92.4% pass accuracy is built on 2,317 passes in a system where Ajax average 60%+ possession — in a mid-block system, this volume and accuracy would drop significantly.
Methodology
Formula: LOG-Adjusted Score = Base FGA × (Current League Tier ÷ Target League Tier).
Premier League (3.7): 7.2 × (2.8 ÷ 3.7) = 5.45 → 5.5
La Liga (3.7): 7.2 × (2.8 ÷ 3.7) = 5.45 → 5.5
Serie A (3.6): 7.2 × (2.8 ÷ 3.6) = 5.60 → 5.6
Bundesliga (3.6): 7.2 × (2.8 ÷ 3.6) = 5.60 → 5.6
Ligue 1 (3.6): 7.2 × (2.8 ÷ 3.6) = 5.60 → 5.6
Liga Profesional (3.4): 7.2 × (2.8 ÷ 3.4) = 5.93 → 5.9
Jupiler Pro League (2.5): 7.2 × (2.8 ÷ 2.5) = 8.06 → 8.1
Critical caveat — The Ajax Possession Inflation Effect: Baas's 2,317 passes and 92.4% accuracy are built on Ajax's system averaging 60%+ possession. In a Premier League or Serie A context where possession is more evenly split, his pass volume would drop by ~30-40% and his accuracy would face more pressure from aggressive pressing. The 250+ line-breaking passes are impressive but must be verified in isolated footage — are they progressive passes that break lines, or safe sideways passes in a system with ample time and space? The Liverpool interest (Arne Slot) is logical — Slot's system at Feyenoord and Liverpool demands exactly this profile: left-footed, composed, high-volume passer from the back. But Slot also demands physical robustness and aerial dominance that Baas's 182cm/48.9% aerial duel rate may not provide.
Read before sending to a club: This projection sits on an estimated base with zero confirmed T3 metrics, derived from a LOG 2.8 league with significant system inflation. The margin of error is wide. The top-5 league projections (5.5–5.6) suggest a squad rotation player or lower-half starter, not an elite signing. Do not use these figures in any client-facing material without heavy qualification and mandatory T3 validation against elite European opposition. The Jupiler Pro League projection (8.1) suggests he would be a standout in Belgium — a useful fallback.
Top 10 Philosophy Fits
Tactical Archetype
"The Cruyff Ball-Playing CB with Elite Distribution" — DMA ~9.0 (92.4% pass accuracy, 2,317 passes, 250+ line-breaking) + OBI_P ~7.5 (35 interceptions, 57 tackles, 140 recoveries) + CLM ~8.0 (composure under pressure) = the complete modern ball-playing centre-back archetype. The 2025-26 season confirmed what the 2023-24 NEC loan hinted at: this is a defender who controls games through distribution. The partnership with Šutalo (17 matches, 4 clean sheets) and the 27 starts alongside Mika Godts show he functions as the left-sided anchor in a progressive back three or back four. Cruyff first. Guardiola second. Mourinho never. The question for top-5 translation is not his passing — it is whether his 182cm frame and 48.9% aerial win rate can survive against elite physical forwards.

Physical Profile
Injury & Medical History
✓ Positive Filters
- 92.4% pass accuracy — #1 in Eredivisie (900+ passes) — Elite composure and technical quality on the ball. Not just accurate — accurate under pressure.
- 2,317 passes attempted — most in Eredivisie — The metronome of Ajax's build-up. Every attack starts with him.
- 89.2% pass accuracy in opponent's half — #1 (200+ passes) — Progressive passing under pressure. This is the differentiator between a safe passer and a playmaker.
- 250+ line-breaking passes — among Eredivisie best — Passes that split defensive lines and advance play. Most aimed at Mika Godts — tactical chemistry confirmed.
- 140 ball recoveries — most at Ajax — Elite off-the-ball work rate for a centre-back. 57 tackles, 35 interceptions, 31 blocks, 137 clearances.
- Ajax Player of the Year 2025-26 + Talent of the Year 2024-25 — Back-to-back individual recognition. The trajectory is undeniable.
- Left-footed centre-back — tactical rarity and value — Left-sided CBs who can play in a back three or back four are in high demand. Enables balanced build-up.
- 4 goals in 2025-26 from centre-back — Set-piece threat and attacking contribution. Not just a defensive asset.
- Contract until 2028 — long-term club control — Ajax hold leverage. No release clause reported.
- 23 years old — 5+ years of development runway — Physical, technical, and tactical attributes all have room to improve. Peak years: 26-30 for a CB.
- 2 yellow cards in 2,760 minutes — exceptional discipline — Stays calm, doesn't commit unnecessary fouls. Red card vs Slavia Prague was a tactical second yellow, not aggression.
- NEC loan (2023-24) proved adaptability — 30 apps at a mid-table club outside the Ajax bubble. Can function without the Ajax possession safety net.
⚠ Caution Signals
- Eredivisie LOG 2.8 — significantly below top-5 standard — 92.4% pass accuracy in the Eredivisie does not equal 92.4% in the Premier League. The competitive gap is real.
- Ajax possession dominance (60%+) inflates passing stats — More time on the ball = more passes = higher accuracy. In a 50-50 possession split, volume drops ~30-40%.
- Aerial duels won: 48.9% (45/92) — below 50% — For a centre-back, this is a concern. Elite PL/Serie A target men (Haaland, Vlahović, Kane) will exploit this.
- Height 182cm — slightly undersized for elite CB — Van Dijk (193cm), Dias (187cm), Gvardiol (185cm). Baas is on the smaller side for a top-5 league CB.
- 0 Netherlands senior caps at 23 — Koeman called him up but didn't play him. Then omitted him. Either tactical mismatch or concerns about readiness.
- 0/16 T3 metrics confirmed — No video validation of any Empire FGA metric. All assessments are statistical proxies from a lower-tier league.
- Injury history: syndesmosis tear (2023) + groin (2025) — Two significant injuries in three years. Durability at elite level unproven.
- Red card vs Slavia Prague (Oct 2024) — Second yellow for a tactical foul. Shows composure can crack under European pressure.
✗ Critical Gaps
- No T3 video assessment completed — The single biggest gap. Every metric is a guess until a scout watches him play in isolated footage against elite opposition.
- DMA 9.0 is a T1 proxy from LOG 2.8 with system inflation — not confirmed — 92.4% pass accuracy in Ajax's 60%+ possession system is different from 92.4% against elite pressing. T3 must verify passing quality under pressure.
- No top-5 league minutes — Every minute of his senior career has been in the Eerste Divisie, Eredivisie, or NEC loan. The step-up is the great unknown.
- No European knockout football experience — 8 UCL group stage apps in 2025-26, but Ajax crashed out. No Europa League knockout minutes beyond group stage.
- Aerial dominance unverified against elite forwards — 48.9% aerial win rate in the Eredivisie suggests he will struggle against PL/Serie A physicality. T3 must verify.
- Physical robustness in high-press system unknown — Can he sustain 90 minutes in a Slot/Liverpool high-intensity system? The groin injury and syndesmosis tear raise questions.
- The De Ligt / Timber precedent vs. the Magallán / Wöber template — Ajax has produced elite CBs (De Ligt, Timber) and failures (Magallán, Wöber). Which template does Baas follow?
- Resale risk if the step-up fails — A €20M+ transfer with no buy-back clause creates asymmetric risk for the acquiring club.
◆ Empire FGA Verdict
FGA 7.2 — Eredivisie CB · Ajax Player of the Year · Elite Ball-Playing Defender · Build-Up Metronome · Netherlands Prospect. The T1 data is the most impressive in the Empire FGA pilot series for a ball-playing centre-back under 24: 92.4% pass accuracy, 2,317 passes, 250+ line-breaking passes, 140 recoveries, 35 interceptions. But the Eredivisie LOG of 2.8 and Ajax possession inflation are the critical confounding variables. Cross-league projections suggest 5.5–5.6 in the top-5 leagues — a squad rotation player or lower-half starter, not a guaranteed elite signing. The Jupiler Pro League projection (8.1) suggests he would dominate in Belgium — a useful fallback. The Liverpool interest (Arne Slot) is the most logical top-5 fit — Slot's system demands exactly this profile. But Slot also demands aerial dominance and physical robustness that Baas's 182cm/48.9% aerial rate may not provide. T3 assessment is mandatory before any €20M+ transfer recommendation. Priority context: Ajax 2025-26 vs PSV (LOG 3.0), Ajax vs Barcelona/Real Madrid UCL (LOG 4.0+). DMA and CLM confirmation likely; SII_R, aerial ability, and CHR are the critical unknowns for top-5 translation. Recommended for Ajax retention as build-up anchor; if sold, maximum recommended fee without T3 confirmation: €18M. With T3 confirmation of elite passing under pressure and aerial adequacy: €30M+.
