Former Germany star Gunter Netzer believes Bayern Munich attacker Mario Gotze should leave the Bundesliga.
Gotze has been linked with Tottenham and Liverpool in recent days.
Netzer told BILD: "I get the feeling that he is still looking for his former self.
“He has not developed at all at Bayern. He never really lived up to the expectations at Bayern.
"It depends on his personality whether he should leave Bayern.
"It is not an easy step. Should he stay in Germany or move abroad? A move abroad has done a lot of players good, especially those who have a point to prove.
"[Former Bayern coach] Pep Guardiola once said Gotze is the best player he has trained after Lionel Messi, and I can understand that comment. Mario has some incredible skills.
"But they are of no use when you are not showing it on the pitch. He has to prove himself all over again."
