Franz Beckenbauer is a German legend in every sense of the word. That is why Mario Gotze should sit up and take notice of his frank criticism.
The double Ballon d'Or winner was not impressed with Bayern Munich's performance in Wednesday night's 3-0 defeat to Barcelona. Gotze in particular displeased him.
Gotze arrived at the Allianz Arena in 2013 for roughly £30m. The 22-year-old is still considered one of the most exciting midfielders in world football, and was linked with every big club in Europe before his big money move to the Allianz Arena.
"He behaves and moves around on the pitch like a youth player. He just stops moving when he loses a duel. This is the behaviour of a child." Beckenbauer told Sky.
"This kind of behaviour does not fit in at Bayern. It is time for him to grow up.
"He has shown at Dortmund what he can do and we know he is a great talent. But there is still something missing"
The former Bayern manager and player's words will hopefully spur Gotze on to improve his game even more.
Beckenbauer, who won the Ballon d'Or in 1972 and 1976, is always happy to offer his opinion on Bayern Munich, a club who he represented over 400 times.
Does Mario Gotze need to 'grow up'?
