[Albion] Imagine if Roberto Mancini, Sir Alex, Mick McCarthy or Kevin Keegan took over

Out of those managers, who do you think would deliver promotion to the Premier League in one season and who wouldn't?

Mancini - no (not sure how he'd fair without a big budget)
Ferguson - maybe (but changing to a new club at his age may be hard, and Championship players may freeze playing for him)
McCarthy - no (might do it in two seasons)
Keegan - yes (would turn us into an attacking force - great credentials at this level of football)

Ferguson would. he's the best manager ever. although he's now some director at utd.

mancini - no i dont think he would.

McCarthy - maybe - he's a top manager at this level.

Keegan -
