Born in
Rosario, Santa Fe, Bonano represented in his native country
Rosario Central and
Club Atlético River Plate, winning several titles with the latter including five
Argentine Primera División championships. In 2001, at 31, he moved to
FC Barcelona, initially as first-choice; he made his
La Liga debut on 26 August of that year, in a 2–1 away win against
Sevilla FC. After the emergence of
Víctor Valdés from the
Catalans' academy, however, Bonano was deemed surplus to requirements and signed with
Real Murcia CF, joining
Deportivo Alavés in the
Segunda División in summer 2004 following
his team's relegation. With the
Basques, he was instrumental in a
2005 top-flight promotion but,
the following campaign, acted second-fiddle to his compatriot
Franco Costanzo who also played with him at River, as the season ended in relegation. Bonano's last year at Alavés was highly turbulent, being suspended by the club's elusive chairman/owner/manager
Dmitry Piterman after the latter had had a run-in with teammate
Lluís Carreras. He retired at the season's close, aged 38. ==International career==
