Career
Berti began his career in 1988 with popular club Boca Juniors. The red stripe was indeed the club he spent most of his career with, not to mention short spells in between for Parma F.C. and Real Zaragoza. In 1999, Mexican club América acquired total ownership of his rights.
In the Copa Libertadores 2000, when América came to visit his former club Boca Juniors for the first leg match of the semifinals, just minutes before the start of the game Sergio Berti withdraw from playing, arguing being scared for the safety of his family and himself based on the chants of the Barra of Boca Juniors.
America lost that game 4–1 and Sergio Berti never played again with America. In 2001 Berti returned to Argentina and signed for recently promoted team Huracán.
The following year, he had a brief stint at Barcelona South Carolina of Ecuador. His career came to an abrupt end in 2002 at the Scottish Premier League side Livingston after spitting at team-mate Richard Brittain, during a pre-season friendly.
