I think Wolves will come up, i am not a betting man but if i were i would definitely put a quid on them.
Normally however they would be at least 9 points clear with their form. But Cardiff and Sheff Utd are matching them blow for blow, and teams below will start to put a good run together before long, it always happens.
But Wolves are deservedly in the driving seat, they will never have a better chance than now, because if they fail then Nuno will be poached by a prem club.
