For me the biggest thing today was how relentless we were in winning possession back, it was almost Bayern-esque the way our players would hunt the ball down after losing it. Brilliant. You can slowly see LVG's philosophy coming into place, quite exciting when you think about it really.
The only thing for me is our defence. de Gea surely can't be this incredible for too long and someone like Costa or Aguero would have easily put 3-4 past us IMO. Hopefully we get a CB partnership of Rojo and Jones (IMO our two best CB's) going after xmas and with Shaw and Rafael back fit too I think this would help to build some momentum and stability at the back.
Sorry chap... One guy scored once and other hid in his dog house when given chance to score 3-4.
EDIT: Btw De Gea can be this awesome week in week out.
