(Reuters) - Barcelona winger Ousmane Dembele needs to improve his attitude and focus on being more professional even if he does want to leave the La Liga leaders, the club's former championship winning player Rivaldo has said.
Dembele, who joined Barcelona in August 2017 for 105 million euros (93.85 million pounds), suffered injury problems in his first year and this season has been criticised for his behaviour, including turning up late to training and events.
