So watching Man U vs Tottenham on Saturday I couldn't fail to realise how after the Mancs changed formation to 4-3-3 we looked really shakey. The same happened against Newcastle when we were 1-0 up, for the last 20 minutes or so, when Shearer changed things to 4-3-3 Newcastle looked likely to score which they didn't thankfully. So what is it about 4-3-3 that seems to destroy our plans? If anything I would have thought the opposition changing to this formation would give us more room in midfield to get it down and play, and also give us more room in the wide areas to exploit through Lennon and Modric. However we seem to crumble. Is this just concidence or something about the way we set up that makes us weak to the 4-3-3? I would appreciate your insight!!
