Iranian basketball star Hamed Haddadi isn't happy with his role in Memphis.

"Grizzlies' officials don't let me show my abilities. I have done my best every time I was called up to play for my team, but I don't know why they don't trust me," Haddadi told Mehr News.

"I want to play regularly for the Grizzlies; nevertheless I will have to change my team now since I am a star of the team but sitting on the bench."
