Arsenal boss Arsene Wenger admits he has defensive concerns with Philippe Senderos getting injured in last night's 1-1 Carling Cup semi draw against Tottenham.
Wenger admitted: "Djourou was injured, Senderos is injured, Van Persie got injured. So, we had no injuries before the game started but tonight considering that we lost three players, and we lost three players in the African Nations Cup, we lost suddenly in one night six players... basically in two days - that is very difficult for us."
