Barcelona great Rivaldo says coach Quique Setien needs to rethink his tactics.

Luis Suarez's return to action hasn't had the impact many thought and it says a lot that Martin Braithwaite has looked more at ease in Setien's system than Antoine Griezmann.

"It's obvious that Barcelona have to improve their football, and that's up to the coach, Setien has to find a formula to do something new," Rivaldo explained in an interview with Betfair at the Camp Nou.

"He needs to find a way to take advantage of the quality of the players he has at his disposal.

"Of course, recent matches make everyone doubt the progress because we're used to seeing a different kind of Barcelona."
