Well. I literally cannot remember a game that changed so instantly and so completely with a tactical switch. Suddenly from looking like neither team would score all day it looked like both teams could score. The speed returned to our game and we made more chances after the change than we did for a long time before it. I must say that a better team would have scored against us, so I dont see the diamond as the undisputed answer to all our prayers. But it simply worked miles better than the back 3.
That said I dont think the back four was the only difference. ADM up front was fine to experiement with, but we can surely conclude that it doesnt work. If we're pushed really far back defending a narrow lead like against Arsenal it might be an option for a breakaway goal, but watching him bounce off their centre backs was just a bit pathetic. When he started playing from deeper he looked so much better that I can't see him not playing there in future.
Falcao - well, its a funny one. If Wilson had had those two good chances (the volley in the first half then the header in the second) I'd have said he'd done nothing wrong, both were on target and well struck. But a £45M striker should be burying both of those tbh, never mind if they were tough chances (which they probably weren't). The only positive thing to say I'd that it looks like a confidence thing to me (which can return) as opposed to a fitness thing (which may not). But with Wilson scoring and offering a bit of pace, and with RVP being teacher's pet, I can see a return to the bench looming for him.
Rooney in midfield has to stop. Ive never liked him there, too many hollywood balls. I noticed today he has a tendency to switch the direction of play when it doesnt need switching. Its a small thing, but the play would be moving from right to left, and rather than one touch sweep it out wide, he's taking three touches to turn back the other way, just so he can ping that ball to Valencia. We need a playmaker in there who understands the flow of the game, not a number 10/9 who happens to be strong enough that he doesnt get knocked off.
Also a quick note on Blind - what a dude. Love watching him play. Not flashy, but tackling neatly, passing neatly, intercepting neatly and tactially spot on in every position he's played for us. If our centre backs were all like him we could switch between a back 3 and back 4 without a problem.
In the end theres pros and cons to take away. We eventually played some good football, we took 3 points from a team that have only lost twice at home this season and, even though he was a little late, LVG saw the back 3 didnt work and ditched it. On the other hand both in terms of the players performances and the initial selection from the manager, it was far from perfect.
