You say if we play Carrick and Fletcher, but that's what we have been playing and we've been getting bossed. Only time we didn't was against Porto where the midfield was ours and Fletcher didn't play that game. Fletcher has looked very lightweight in recent weeks, he's been getting knocked about far more than he was at the start of the season.
I also wouldn't play Nani (I know, I'm sure I surprise a lot of people with that statement). I would rather play Park for sure and have him track Pienaar all over the park on the right then let Ronaldo roam free.
