What will be interesting to see is how Lambert manages the few creative attacking players we have on the books. We desperately lack people that can run with the ball, at the moment its pretty much Costa, bringing Cav and Graham will help a lot in that department but the manager has to pick them. Similar problem with central midfield, in order to accomodate Dangerous Dave we are sacrificing a creative player (Evans is about it at the moment with Ronan out) and again the manager has to choose to play them.
I know Cav was very hit and miss, but he would create Chaos for the other side, which helps Costa so much and I am sure Graham would do the same.
It all rests on Lambert, he does have the players to create a more balanced side, if he doesn't do that he can have no argument about getting the boot.
