Arsenal manager Arsene Wenger believes that the win against Manchester City will strengthen his side's belief and confidence in the title race.

The Gunners opened up a gap of four points between themselves and third-placed City with the 2-1 victory at the Emirates Stadium on Monday night and Wenger feels it has further strengthened their premiership credentials.

"Every win strengthens your belief," Wenger said.

"When it's a big game like that, of course (it does) even more but what we want is to take care of our performances and our spirit.

"I think we have something really special there and we keep good desire to improve and realise that you have to earn the right to win in these games. That's what we did today.

"Our belief is stronger. We have played many very, very young teams but there is more maturity now in the side. You can see in these games it comes out.

"When you are under pressure, we can deal with it. We are very ambitious but this league is very difficult so that makes you very cautious as well.

"I think it gives us confidence and strengthens the belief of the team. As well, it makes us realise coming out of the game tonight there is a very long way to go.

"Every game is a battle and as soon as you lose a bit of that effort, you have no chance in this league."
