Hleb has spent the season on loan at Stuttgart is not keen to stay at the club while Christian Gross is in charge.
“I have two years left on my contract with Barcelona, I am moving back to the club as I have the ambition to show myself, as much as other people, that I am able to perform at the highest level,” he told Bild newspaper.
“He criticised me from the first day of his reign. He did so when I dribbled with the ball, he did so when I did not play the ball fast enough,” he added on Stuttgart boss Gross.
“I got the feeling that everything I did would be wrong in his eyes.
“He attempted to transform me into a different player. What made me successful in the last 10 years, he was trying to change.
“I have respect for him and his achievement after taking the club over, but I failed to get along with him personally. It did not fit.”
