I don't necessarily think that it does. I agree by pushing forward it makes the other team sit deeper however should they play on the counter and get in behind our midfield our current back 4 would be helpless. It seems to me that this is the decision NA as arrived at hence 'the wall' of 4 midfielders we currently have.
Also every time I see is trying to be more expansive it results on conceding lots more goals.
But I agree with your thoughts that we need to be more attacking but I think we need more than 1 player to be doing that given the players obvious limitations.
