Most of his professional career was spent in Spain, where he arrived at the age of 18, going on to represent six clubs in more than one decade with totals of 244 games and 43 goals, 145/18 in La Liga.
Born in Arroyo Seco, Santa Fe, Biagini started his career at Newell's Old Boys in the Primera División, in 1993. In 1995, he was a main part of the Argentina under-20 team that won the FIFA World Cup in Qatar.
Biagini signed for Atlético Madrid at just 18, being an important attacking element as the capital club won the double in his first year. He was mainly and regularly used as a substitute for countryman Juan Esnáider and Kiko during his spell and, after a poor second season, moved to fellow league side CP Mérida in the 1997 summer, where he would be eventually relegated.
Biagini then played five seasons with RCD Mallorca where, safe for his first year where he scored a career-best 11 goals (also helping the team to the final of the 1998–99 UEFA Cup Winners' Cup by scoring the 1–0 winner against Chelsea in the last-four's second leg, in a 2–1 aggregate success), he would be very scarcely used, also serving a six-month loan to England's Portsmouth in the Championship, where he found the net against Millwall and Wimbledon.
Biagini returned to Spain for 2002–03, being part of the side than won the campaign's Copa del Rey and being subsequently released by Mallorca. After four additional years in the Spanish second division, in representation of three teams, he returned home and joined Arsenal de Sarandí.
