Julio Arca is backing Middlesbrough teammate Tuncay Sanli to break his duck.

"Tuncay was unlucky in his finishing (against West Ham)," said the Argentinian. "We know how good he is and we have seen how well he can finish in training and friendlies, he will do well for us.

"Strikers rely on scoring the first goal for a club and when he scores his first he will go on and get more goals. We're all sure of that."
