Tomas Rosicky accepts that Arsenal's title prospects will rise and fall on their ability to beat the cream of the Premier League.

A defeat at Chelsea before the international break knocked Arsène Wenger's team out of its stride and another major contender lies in their path on Sunday - Manchester City.

Rosicky scored on his comeback from injury at Eastlands last year but Arsenal lost the game 4-2 and have faltered against the top flight's elite in recent outings. They impressed at Stamford Bridge at the start of this month but came away empty-handed and Rosicky knows this has to stop.

"We need a win in Manchester," he said. "We cannot always say we are unlucky because it doesn’t work like that. It’s time to prove we can win those games.

"At Chelsea it was the same old story. We presented ourselves well on the pitch and we were very disappointed with the result because you go into the game with the feeling you can win it. But these are all just words and we have to finally show it on the pitch.

"We have a great opportunity to do that on Sunday. The win over Shakhtar was a good boost for us before City, so let’s go for it there."

Roberto Mancini's team lie second in the table, three points adrift of leaders Chelsea and two clear of Arsenal, Manchester United and Tottenham. City are scaling new heights in the Premier League and Rosicky is not surprised.

"If you have this [spending] power you can almost buy whoever you want, so I’m not surprised," he said.

"I don't know if they can stay there. They are a tough team if you see them play and they are tactically very good. Sometimes they are not so entertaining but they are a little bit similar to Chelsea. They play great in defence, they are very solid at the back so we need a good performance and we need to be clinical."
