It would take a lot of money to replace Roberts, just don't get all the criticism he gets, if he's not directly involved, ( ie showing in stats as assist or goal people have a go at him. Without realising that a lot of goals he is involved in the build up to the goal
The problem for me is that while he does ok generally he could and should do a lot better. Misses virtually every chance he gets and he gets his fair share. Attacks break down too often when he's on the ball.
Clarke, Mundle and Watson have all clearly shown what we're missing on the opposite wing.
