If Wenger is guilty of anything it's giving youth a chance. He could have gone out and brought in an established midfielder to replace Vieira but instead has given the likes of Fabregas and Flamini the chance to play in the first team. Arsenal have been without their entire first choice back four for whatever reasons in the past month or so (Lauren, Campbell, Toure, Cole) and as a direct result have lost games they otherwise would not have. The recent results have knocked the confidence out of the younger players but they will learn from the experience. If Arsenal are still within 4/5 points of fourth spot going in to the last month of the season then they will over take Spurs - just look at Spurs' last few games of the season : Everton (A), Man Utd (H), Arsenal (A), Bolton (H), West Ham (A).
