Arsene Wenger believes Arsenal have the capability of making a strong challenge for the Barclays Premier League title.

The Gunners extended their unbeaten run to 13 games in all competitions with a 4-1 victory against Wolves.

Wenger is keen to get his hands on the title again and said: "The desire is there. We just want to strengthen our belief."

He added: "The most important factor is we play for each other as we do. We have to focus on our performance and continue to develop our style of play.

"We were out of it (the title race) last year after we lost five games in 14. Two years ago, though, we were close to winning it, people forget that. We will keep our humility and play our game.''

Wolves made a bright start but were undone by own goals from Ronald Zubar and Jody Craddock.

Cesc Fabregas and Andrey Arshavin extended their lead before Craddock scored for the second time, at the right end.

It means they keep the pressure on Chelsea and Manchester United who meet on Sunday at Stamford Bridge.

Wenger will not read too much into the scoreline between Chelsea and United - and does not rule out Liverpool to restore their challenge.

He said: "It is too early to calculate too much. Sunday is fantastic for us. Let's hope it is a good game and you enjoy it. You always enjoy a game when you have won. Also, I would not discount Liverpool at the moment, even though they have lost five games. Now everyone has lost two, so there is a difference between now and last year."
