The Gunners continue their pre-season preparations at the Amsterdam Tournament later this week. The likes of Emmanuel Adebayor, Theo Walcott and Tomas Rosicky are set to return for the two games, against Lazio on Thursday and then hosts Ajax at the weekend. Having seen some of his fringe players impress during their Emirates Cup triumph, most notably young Danish striker Nicklas Bendtner, Wenger has faith in the progression policy which has helped nurture many of the current first-team squad. "We have bought Eduardo (Da Silva), and we have Bendtner and Walcott to take over from these players," said Wenger, hopeful his main summer arrival will get clearance on a work permit from the Home Office later this week. "You can not say Walcott is a potential world-class player and then, when we have to play him, ask why we do not sign another world-class player. You can not have it both ways." Wenger was happy enough with the performances against Paris St Germain and Inter, feeling it had restored some belief to the squad following last season's disappointments and the sale of talisman Thierry Henry to Barcelona. However, their Achilles heel was proven to be once again defending crosses, with Honduras striker David Suazo headed the Italians into the lead on Sunday before the Gunners rallied and eventually won the match through a sublime piece of skill from Robin van Persie. Wenger reflected: "In the air, we have to be more efficient. "We have to work on that because in England that is an important way to stop goals. "[Philippe] Senderos played very well on Saturday and he is very good in the air. We still have [Johan] Djourou, who is injured at the moment, so I do not want to buy a centre-back." One player set to be integral to Wenger's plans next season is midfielder Cesc Fabregas. Although more than aware of the need to protect against burnout following more than 50 appearances during the last campaign, the 20-year-old is eager to be involved as much as possible again. "I want to play every game if I can," he said. "Of course, physically, you cannot always be 100%. You have to be professional off the pitch as well, try to eat well when you can. "Even if I say 'I do not want to play the Carling Cup', when it comes I will want to play and get angry if I am not involved. That is the way I am."
