the problem was we DIDN'T really build the team around him,we had a lot of (poorly performing) square pegs in round holes last season,this year with wingers is where we should have seena lot more of Diego.
as for the 4-4-2,this is the same formation we stuck to rigidly for years and yes IT CAN be succesful,but think about every team that plays the 4-4-2 well and they all have marauding fullbacks that overlap and allow the wingers more space in which to play.
do you honestly think we have the players to do this well,or,like me,do you fear that we are going to have 2 fullbacks that hate to get over the halfway line,2 wingers left high and dry as the opponents double up on them and a midfield pairing so lacking in pace that we are completely overrun in the middle?
god will be be crying for some creativity then.........
