There's not always a single person at fault and I think that's the case here. Should be have been closed down quicker for the cross; one of the three/four defenders in the box should have better tracked the run into the box and alternatively Ben could have come and got it.
You know that we do actually agree on the Ben not commanding his area point too; I've said many times that it's the weakest part of his game. The difference though, is that I can recognise that his strengths massively outweigh his weaknesses and he's a fantastic keeper.
