Eljero Elia admits he's frustrated at Hamburg.
The Dutch winger was linked with Liverpool and Manchester City in January.
"Apparently there is not much confidence in me," he told Voetbal International.
"That hurts. I feel strong and would like to show the fans what I can do. It is very frustrating. I have started eight games and we have won seven of them so I cannot have done that badly.
"I don't know what I have done wrong, I have not been told. I know that I am not a bad player and I am in good shape.
"I am a player who needs confidence. If I play every week I will improve. No-one can accuse me of not working hard enough, I am as fit as a fiddle."
