A recent product of Boca's academy, per the source, able to play central defense or left-back. A good, reliable marker without much comfort on the ball — his main weakness is struggling to play out from the back cleanly, often resorting to long clearances instead. Squeezed for minutes behind more experienced options, though the source notes Veira had shown real interest in developing him by giving him regular chances the previous season.
Made his senior debut for Boca's first team against Platense, per the source — though the exact date the database records for that debut (8 May 1977) is identical to Matellán's own birth date, which looks like a data-entry error in the original file rather than an actual match date.
