Barcelona midfielder Alex Hleb has slammed Stuttgart coach Christian Gross over the way he was treated while on-loan at the Bundesliga club.

The former Arsenal star failed to make an impression at Stuttgart this term.

Hleb, who failed to impress in his first season at the Nou Camp before being loaned out last summer, told Bild: "I'm going back to FC Barcelona, where I have a two year contract.

"I want to go there and make the breakthrough. I want to prove to myself and everyone else that I can play at the highest level."

As for his relationship with Gross, Hleb said: "From day one he has criticised me. If I'm dribbling, he has criticised me. If I have not played the ball right back, he has criticised me. I have the feeling that everything I do is wrong."
