Robert Lewandowski’s agent has hit back against Dietmar Hamann’s remarks that the pole is the “problem” for Bayern Munich.

The Bavarian’s seven-match winning run in the Bundesliga came to an end on Saturday, when they lost 3-1 to Bayer Leverkusen at the BayArena.

Bayern fell prey to new Leverkusen coach Peter Bosz’s offensive tactics in the second-half with Leon Bailey, Kevin Volland and Lucas Alario sealing the three points.

Leon Goretzka was the sole scorer for Bayern on the day as the normally prolific Lewandowski was kept subdued by the Leverkusen defence.

The result demoted Bayern to third in the Bundesliga and seven points behind leaders Borussia Dortmund.

Speaking afterwards, Hamann claimed that Lewandowski has become a problem for the German champions as he’s a bit of a “lone wolf”.

“I think Lewandowski has become a problem for Bayern Munich,” Hamann told Sky.

“His theatricality, his gestures of refusal, his sometimes listless behaviour on the pitch. I think it’s obvious that he’s a lone wolf.”

“As a Bayern Munich striker, you must also have a value for the team if you don’t score goals.

Bayern Munich have reportedly become the latest club to show an interest in signing Barcelona's Ivan Rakitic.

“For me, he doesn’t have that at the moment. I believe that he doesn’t have too many friends in the team or that he’s sometimes controversial.”

Lewandowski’s agent, Maik Barthel, has now hit back against Hamann’s comments and suggested that the former Liverpool star isn’t qualified to make such comments.

“After losing to Leverkusen, it doesn’t help to attack players at this level as Mr. Hamann did,” Barthel told Bild.

“To me, the fact that he believes Robert is the main cause says something about his tactical understanding. Maybe he didn’t watch the game.”

Lewandowski has managed an impressive 24 goals and seven assists in 27 appearances across all competitions this season for Bayern.

The Poland international is contracted at the Allianz Arena until June 2021.
