Arsenal manager Arsene Wenger said on Tuesday he'd all but given up on the idea of Dutch striker Robin van Persie playing for the English Premier League club again this season.

However, he stressed the player would regain full fitness and once more be a force at top-flight level.

The 26-year-old forward suffered a right ankle injury while on international duty in November.

The Gunners had hoped the striker might be out for six weeks but instead he needed surgery and Wenger believes the best van Persie and Arsenal can hope for is a return towards the end of the current campaign.

"If you are very positive you would say (he'll be back in) April," Wenger told the club's website. "If you're a bit cautious you say May. It is virtually the rest of the season.

"Personally, I thought 'let's put it in my head that he will not play again this season and hope that I will have a good surprise'," the Frenchman said.

However, Wenger is confident van Persie will bounce back from the injury and rediscover his top form next season.

"When you have such a big surgery there is one thing that is important first of all, and that is the option of the surgeon, will he be the player he was before? We had a clear answer. 'Yes'," Wenger said.

"The second thing that is very important in the first stage after surgery is has he an infection or not? He hasn't.

"The third thing is patience. At the moment he cannot do anything, he is just sitting at home waiting until he can work again. The first two steps have been very successful."

Van Persie's injury has led to speculation Wenger will move for another forward when the transfer window re-opens next month.

Arsenal are third in the Premier League and through to the knockout stages of the Champions League.

Wenger said he would have no concern in signing a player in January who was cup-tied for the Champions League, just as he did when bringing influential Russia forward Andrey Arshavin to north London at the same stage last season.

"Yes, I would," Wenger said when asked. "We are going for the domestic title and the FA Cup as well and doing what allows you to rest a player for the Champions League or play another player in the Premier League."
