Former Barcelona goalkeeper Vitor Baia has supported Deco's claims that Pep Guardiola needs to prove himself at another club. Deco made the comments over the weekend.
And Baia agrees: "Pep has done something extraordinary at Barca but has to demonstrate the same away from the club. It's true that to reach the level of Jose Mourinho, Pep has to win titles in other leagues.
"He has time to prove he can do well in other countries like Mourinho has done."
