Tottenham manager Harry Redknapp says Giovani dos Santos must quit partying if he is to fulfil his potential.
Dos Santos has struggled to feature regularly for Spurs and has spent time on loan at Ipswich and Galatasaray following his move from Barcelona in 2008.
The 21-year-old was late for training because of his clubbing habits, according to Redknapp, who believes the schemer can be a 'top player' if he tries.
And after an impressive World Cup finals with national team Mexico, the White Hart Lane chief is looking forward to seeing if the midfielder can change his ways this season.
"If he could pass a nightclub as well as he can pass a ball, he would be all right," Redknapp said in the Daily Star.
"His mum and dad came over to see me last year and he apologised because they realised he wasn't dedicated.
"He's got bags of ability and fantastic skill. Suddenly he was late on Monday mornings...upset stomach.
"He'd probably been in Barcelona partying somewhere. He has had a great World Cup. If he knuckles down this year, he could be a top player."
