As has been stated time and again, our back up players are truely pathetic. That's the difference between United and us, they can afford to lose a few first teamers and still get a result, we lose a few first teamers and we are woeful. Arshavin, Denilson, Rosicky, Diaby, Chamakh all disgraceful, our defending was a mess and Van Persie totally isolated. Wenger needs to seriously think about what tactics to play when United come to the Emirates because this same rubbish will happen time and again.
