Despite arriving with an incredible reputation, Ousmane Dembélé's Barcelona career has been plagued with poor discipline and disappointing performances.
Dembele has been consistently linked with a move away from the Nou Camp, and was recently disciplined by the club after turning up late for training.
Rivaldo, however, feels like there is a future for him at the club, only if he improves his discipline.
"Ousmane Dembele's situation at Barcelona is upsetting because he's already shown that he can play very well, score goals and be an important member of the team.
"He just needs to focus on being a little more professional and to stop being late for training sessions", Rivaldo told 'Betfair'.
"This is not the correct mentality for someone potentially trying to leave Barcelona. It's always strange to hear that someone might want to leave a big club in this way. Anyway, if he wants to leave, he must prove his value by playing well and not missing training sessions to recover his credibility as a professional. If he doesn't change, he is hurting himself more than the club."
"This isn't easy for Barca either. They can't simply control all players' steps as they have their own personal lives. Even if you alert the player about his behaviour, you can't do anything else as you would be chasing him all the time.
"I think this is more a job for a family member, friends or the player's manager - basically his support network. They should remember that this could undermine his career which would be a pity for such a talented player", he added.
