Former Germany international and Bayern legend Matthaus have been a vocal critic of the club's recent approach, particularly after the match against Augsburg.
“I saw him when I went down after the game, he was really angry and upset that he wasn't substituted," Matthaus said on Sky about Karl. "Normally you can say: 'Okay, I'm 17,' but he wants to play, he's fired up.”
Matthaus expressed his bewilderment over Kompany's choices and further shared his message to the club, citing last season's Champions League exit at the hands of Inter. He added: "It didn't work against Inter, as Kompany was accused of, but he always tries with these older players, like Boey, who didn't deliver what was expected of them. If you have a campus like this, you should also use it in the professional arena."
