Where were the leaders? A self induced capitulation

No game is easy, but to concede three at home to West Brom is frankly nothing other than woeful. A late equaliser may have papered over the cracks and salvaged a point, but perhaps in the long run it is better than we have not avoided this hefty kick in the nuts.I think Arsene got the starting midfield wrong. The middle trio of the unfit Diaby, Song and Eboue just doesn't have the right balance
