Arsène Wenger believes Sunday's victory at Manchester City could be a turning point in Arsenal's season.

Goals from Samir Nasri, Alex Song and Nicklas Bendtner secured a 3-0 win at Eastlands after City had Dedryck Boyata sent off in the fourth minute.

The result left Arsenal just five points behind the Premier League leaders, Chelsea, but just as importantly it boosted the Gunners' self-confidence after a poor run against their direct rivals for the title.

"It was certainly a pivotal moment of our season because we could not afford a defeat," admitted Wenger.

"To keep in touch with the top teams and to go out and have a victory was mentally very important for the team. Overall I believe it is a consequence of intelligent attitude and good team and collective spirit - that’s why we got the result.

"Even though it was under special circumstances I still believe it was difficult to beat Manchester City, even though they played with ten men. Because we as well played many times with ten men and we still have not lost the game."

Arsenal's upsurge in form has coincided with the return of a number of players from injury, leaving Wenger with plenty of options as the fixtures come thick and fast.

Sunday's substitutes bench was packed with internationals including Theo Walcott, Tomas Rosicky and Nicklas Bendtner. According to Wenger, it goes to show how strong Arsenal's squad is.

"I always spent a lot of time to convince everybody [about that]," he said. "Now I think people realise when everybody is fit.

"Remember we still have Thomas Vermaelen, Robin van Persie and Aaron Ramsey out and all these players will come back. I am convinced we have a very strong squad."
