In all fairness, if Leicester lose today, Pearson will likely be out of the job. I can imagine that Utd may wait to see how it pans out with a new gaffer in charge, before making a decision on Nick's future.
Leicester has been a disastrous loan spell but there is no way on earth that Utd will send him over to us (as much as I would love that to happen). League One is well below the level that they need him to be playing at. He will probably go to a Championship club and Bolton - particularly with Lennon now there - wouldn't be a bad shout at all.
