Yeah I think this was their major problem, Toure and Zabaleta let their midfield down, although their defence has also got lots of problems! Still we took full advantage and Koeman got his tactics spot on. We certainly look better playing 3-5-2 and it seems to suit the players we've got.
Got to say I'm not a fan of 3-5-2 but we looked solid as a rock yesterday with it ( apart from the odd brainfart from Mori lol )
His tactics were spot on and I've mentioned a few times in various threads his substitutions were superb, right players at the right time.
