Rated by the source as the squad's biggest long-term prospect: highly skillful, undersized but good at shielding the ball, precise in possession and capable of beating defenders with quick dribbling. Projected as Veira's backup option in the enganche role behind Maradona and Latorre.
Debuted in the Argentine first division for Argentinos Juniors on 10 March 1996 against Racing (1-3), before moving to Boca. Diego Maradona himself is cited in the source as having called Lapaglia one of the best young players Argentine football would produce in the years ahead — with the caveat that everything depends on his progression continuing and on handling the pressure of playing for Boca.
