It may due to William is former Chelsea Man. But we should have give him a change to prove that his ability to bring the the others young player to towards TITLE CHALLANGE.....
according to Wenger, centre defender is a good position to be given the are band, because they can see more problems on the field, also Gallas is a well exprienced player!!
But i just worried others Arsenal Player feeling........Especially Gilberto Silva and Kolo Toure......That is simply because William was just only spend one (1) season in Arsenal and now that is his second Season.......But may be this is Arsene Wenger decision to have 3 continous France man Captain........from Viera to Henry and now William gallas......
