Former Germany star Gunter Netzer has stated that Bayern Munich midfielder Mario Gotze will have to prove himself all over again.

Gotze was regarded as one of the finest attacking midfielders in the world not too long ago and the 24-year-old was the player who scored the winning goal in the 2014 FIFA World Cup.

Despite his undoubted talent and exploits at such a relatively young age, Gotze has struggled to forge a regular spot in the Bayern first team in recent seasons and ex-Germany international Netzer believes that the former Borussia Dortmund man now needs to prove himself to the world once again.

"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," Netzer told German paper Sport Bild of the Tottenham target.

"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."
