With striker Nicklas Bendtner set to sit out tomorrow's Champions League clash with Olympiacos at Emirates Stadium after suffering minor bruises when his car went off the road, Dutchman Van Persie will again be leading the Arsenal attack.

Van Persie's well-executed finish against Fulham proved enough to take all three points in their Premier League match on Saturday, when the Gunners were up against it for long spells and had rookie goalkeeper Vito Mannone to thank for a man-of-the-match display.

The Dutch international, 26, had also made the pre-match headlines when admitting he has exaggerated when he has been pushed by a defender.

By so doing, Van Persie weighed into the diving debate after team-mate Eduardo was banned by UEFA, a decision which was subsequently overturned, following an incident against Celtic in the Champions League qualifier.

Wenger, though, feels Van Persie has a point.

"Sometimes when a striker is fouled, he wants to make sure the referee sees that, which is what basically Robin was talking about," said the Arsenal manager.

"He wanted to show there is a difference between what people call diving and being fouled.

"In fact, the television showed a great example of it at Manchester United when a penalty was not given when [Patrice] Evra fouled Van Persie 100%.

"He had to go down, but when you go down, you make sure the referee notices you have been fouled."

Winger Theo Walcott may be in line to feature at the weekend, having not played at all this season because of a back problem, which have hit his England chances.

Wenger said: "He is short of competitive action at the moment, he needs a game and we will organise a game for him."

Midfielder Denilson is, however, set for an extended spell on the sidelines because of a fracture to his back.

Wenger feels he has plenty of cover, with both Abou Diaby and Czech international Tomas Rosicky challenging for a starting place tomorrow.

"We have plenty of options," said Wenger.

"We have a very big squad at the moment and there are opportunities there for anybody to take.

"Aaron Ramsey is not far away from the first team now and Jack Wilshere who can play when requested, so we have plenty of opportunities for young players to come in."

Olympiacos manager Zico believes his side must be brave if they are to take anything away from the match.

"To be successful against Arsenal it is very important that we pay them the utmost attention, that we leave no space for them," he said.

"They are a very fast team, especially when they attack, especially in the follow-up and we have to concentrate.

"We cannot be fearful and we have to play in a brave way.

"We have to have the mentality that we are equal to any team and on the field it's 11 players versus 11 players and this is the mentality I want."
