Wenger seems scared to admit that his philosophy has failed. He needs to buy some players who are around 25 - 28 & know how to close out games for a win, but instead he insists on buying "potential".
There always seems to be a saga surrounding the arsenal captain each year, Vieira was continually linked with Real Madrid before he finally went to Juventus, Henry was linked with Barca for a few years before he finally went & now Febregas.
