I'm completely with Dave on this: no way would 'El Maestro' come back to us.
After all, he only ever wangled his way into jobs with clubs who were doing well by their standards, or in our case, recent standards.
Swansea had won promotion, missed out in the play-offs for a second successive promotion, won 3 cups and had 2 trips to Wembley in the two seasons before he took over.
Wigan had finished comfortably in mid-table under those two managerial giants, Paul Jewell and Steve Bruce. The Roberto took over and he soon had them passing their way into the Championship. It's only now that they are showing signs of recovering from this catastrophe.
He left Wigan with the bizarre statement that he "wasn't the right man to bring them back up" and joined us on the back of Moyes' record of seven finishes in eight season of 7th or better, the one exception being when we finished 8th. After a good start we got steadily worse as Roberto's influence grew and the Moyes influence faded. Thank God the Carpetbagger put him out of his misery and sacked him otherwise we'd have almost certainly gone the same way as Wigan.
So there's no way that Roberto would come back to us when we're in such a sorry state. He'll be scouring the leagues looking to inherit a good side from a manager who's gone on to better things.
