Manchester United are looking over their shoulders at neighbours Manchester City, admits striker Carlos Tevez. The Argie insisted: "Robinho will greatly improve the quality of Man City. They will be much closer to the top this year.

"He's one of those great players that people want to go and watch because he has a lot of fun playing. Robinho is one of the game's best entertainers but the Premier League defenders won't see it that way.

"The players who have to mark him will be very uncomfortable this season.

"City's squad is looking so strong now. With Robinho, Pablo Zabaleta, Martin Petrov and Elano they have real quality.

"And with all their impressive new signings, the two Manchester derby games could be really significant this season. They are now even more important to win.

"We lost to City twice in the league last year but, even though they are stronger now, we look forward to gaining revenge. They have quality and they also have the defender who marked me the best last season - Micah Richards. Well-built, fast and strong, he is a very good defender."
