I fail to see that YV, cutting out danger at source ie. the cross, what is essentially an assist, (no assist, no goal), is very much the main problem, Sandro not picking up Mata's run would have been an irrelevance.
Yeah, Gallas' attempt at a clearance was clearly the biggest fault. The only reason I brought up Vertonghen is that Huddlestone was being criticised for not very much when the current golden boy for most fans these days was guilty of worse in the same move.
