Carlos Tevez fears his move to Manchester United has stalled his progress.

"I'm not as dangerous," he told the Daily Mail. "I'm not as effective in the penalty area anymore. That is something I have lost, and I have to get that back. I used to score better goals, great goals.

"But something strange has happened. I think it has to do with the fact that the person up front has to do a lot more for the team than just score goals.

"They have to play more for the team and I think I have sacrificed myself recently with regards to that aspect."
