Which managers are on the up in your league though? i.e. which managers could you one day see managing a real world class team?
In the EPL, the obvious choice is Martin O'Neill. Whilst its fair to say that Celtic and Aston Villa aren't exactly small fry, IMO he could walk into a position at any club in the world and do a more than adequate job.
Another name whose been around for a bit is David Moyes - but his style of football probably wouldn't go down too well at most top league clubs.
The revelation of the season in the EPL though surely has to be Zola. Its not just that his team have been doing well - its that they've been playing some of the best and most exciting football in the league to achieve it. If hiddink does indeed leave Chelsea in the summer I wouldn't be at all surprised to see Zola the favourite to replace him. He's done a hell of a lot better than I would have expected Mancini to do.
Brown at Hull is another manager that deserves a mention but inly passinlgy as despuite the great start they've made, they've been on a disastrous run of results and you have to think that a manager with top class potential would have prevented that run.
