 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 victory), he would be very scarcely used due to several injury problems, also serving a six-month loan to England's Portsmouth in the First Division, where he found the net against Millwall and Wimbledon.Biagini returned to Spain and Mallorca for the 2002–03 campaign, being part of the side than won Copa del Rey – even though he did not appear in any matches – and being subsequently released.After four additional years in the Spanish second division, in representation of three teams, he returned home and joined Arsenal de Sarandí.
