Not really sure when it would ever be plainly obvious that 4-3-3 would suit us better than 4-2-3-1 for a particular game to be honest?
Surely you find a system that gets the best out of your best player/s not pick a system and then find the correct pegs for the correct holes? That's putting all your eggs in one basket a bit, it's Rooney, not Messi or Ronaldo
Do you think City's 4-2-2-2 is by design or is it to get the best out of Toure, Silva
and Aguero without pushing them into periphery positions?That formation gets the best out of the 'team' though surely, negredo/nasri/zabaletta/kolarov all benefit from that
If we went 4-3-3 then for me Sturridge would be the one that makes way not Rooney just because he is better with his back to goal, but with 4-3-3 there would be a greater reliance on one of the central 3 to make the runs beyond the striker and close the gap between the two lines more to stop the inevitable long ball over the top (especially in the cimate we are about to go to) due to larger distances between players than the smaller triangles you get naturally from 4-2-3-1. We'd just end up losing possession and chasing shadows - energy sapping.
Nobody should be guarenteed a place, but is Roy knee-jerky enough not to start Rooney?
