Arsène Wenger expects his much-changed Arsenal side to give Olympiacos a sterner test than an unchanged team would have done.

The Frenchman has travelled to Greece with only two of the players that started Saturday's 4-0 win at Wigan - Thomas Vermaelen and Andre Santos - and is set to field an XI with a distinctive 'Carling Cup' flavour.

Wenger's selection may be described as a 'shadow' squad in some quarters but the manager believes the Greek champions would be wrong to expect an easier ride from a group of players that pushed Manchester City all the way last week.

"It is true that some of the players [in this squad] do not play many games but they will be even more motivated to show they deserve to play," said Wenger.

"The game will be more difficult for them than if we had brought the team who played on Saturday. I wanted to bring this team because they gave a hard time to Manchester City last week.

"I left some players at home because I did not want to put players on the bench when there is training at home but this side will be up for it.

"I like to give a chance to young players when they deserve it. I like to do it when I can do it. I have shown in the past that I am not scared to do it when they have the quality to turn up. I believe everyone needs to chance to show their quality. When I am able to give that chance I am always happy."

Arsenal have booked their place in the last 16 of the Champions League but Olympiacos are vying with Marseille and Borussia Dortmund for the second qualifying spot. That's why Wenger wants 100 per cent from his players on Tuesday night.

"I know we have a big responsibility tomorrow," he said. "I would be deeply disappointed if our winning attitude was not right. I will make sure we walk out there with an immense desire to win the game."
