Alves believes the Celtic goalkeeper Forster could be a good substitute for Valdes ahead of next season
"We played three times against Celtic in a year and Forster has always been fantastic," he said.
He added: "He had to face the best strikers in the world and has done very well even when Celtic lost."
Forster was one of the key men of Celtic and his performances have not gone unnoticed so even Alves believes the club could have him in mind for the future. "Barca always takes care of adding quality to squad and it is certain that he has. Obviously there are transfers that can not be done at the moment but if it occurs in the future would be a good option,"
