Fit-again Arsenal striker Robin van Persie is ready to push his body to the limit so he can face Chelsea in their Barclays Premier League showdown at Emirates Stadium on Sunday.

The Dutchman got more than an hour under his belt during Wednesday night's 2-1 win over Steaua Bucharest in the Champions League in what was a first appearance for the Gunners since October 7 because of a knee problem.

Arsenal manager Arsene Wenger felt van Persie "looked sharp", but stopped short of revealing whether he would gamble on risking him from the start against the Blues this weekend.

With the likes of Cesc Fabregas, Mathieu Flamini and Alex Hleb all struggling for fitness, the return of the seven-goal forward would certainly be a welcome boost.

Van Persie declared: "I am fit if the boss picks me. I am available.

"However, I am not 100% yet. You need games. You need rhythm.

"I can easily make 60-65 minutes, but after two months out you cannot make 90 minutes.

"Maybe next time, I can do 75-80 minutes, or come on as a sub - I don't mind."

The Dutchman added: "It can always be better, but I have been out for two months and I'm quite pleased about some passes. I put Theo (Walcott) through a few times and that's my game.

"I want to mix things up, I want to pass the ball and my aim is to be all round player."

Wenger served a one-match touchline ban last night after being sent from the dugout during the previous European tie in Seville.

UEFA are set to discuss the matter when a disciplinary panel meets on Thursday, and could decide to extend the suspension into the knockout stages. A decision is not expected to be announced until Friday.

After they finished runners-up in Group H, Arsenal could face former winners Porto, AC Milan, Barcelona or Real Madrid in the last 16, along with Italian giants Inter Milan.

Immediate attentions, though, turn to domestic action and the visit of title rivals Chelsea to Emirates Stadium on Sunday.

Arsenal players, directors and staff are set to take part in the 'Be a Gooner. Be a Giver' campaign by donating a day's pay to the club's charity of the season, TreeHouse - the national charity for autism education.

Captain William Gallas said: ""We are united on the pitch and we are united off it. We don't want to just talk about helping TreeHouse, we want to make a real difference.

"I hope that the fans can also make a small donation so it will be a real team effort."
