The ex-Portugal star is optimistic about the Camp Nou side's chances at qualification for the next round, and believes Victor Valdes' suspension is too heavy
The Blaugrana were beaten 2-0 at San Siro back in February, but Vitor Baia has little doubt that they will eventually emerge victorious once the home tie is complete.
"Knowing the players, the fans and the club's history, I am confident that Barcelona have what it takes to pull off a historical comeback against Milan," Vitor Baia told La Xarxa.
The former Portugal goalkeeper also had his say on Victor Valdes' four-match ban following his dismissal against Real Madrid, and feels the punishment is rather harsh.
"Valdes' four-game suspension is a very severe punishment," he added. "It's a lot of games for a player who pretty much has a clean sheet when it comes to this kind of behaviour.
"It can be difficult to keep your emotions in check when you think an injustice has happened and that's how Victor must have felt."
Valdes will miss the Primera Division games against Deportivo La Coruna, Rayo Vallecano, Celta Vigo and Real Mallorca due to his ban.
