I think McClaren could do a good job out of what is turning out to be a poor choice list. McClaren is a players man and would have them onside from the start and has good sense of humour (see Dutch radio interview). The motivation for the man to succeed in the wake of the 'brolly' is huge, however if the consensus is so overwhelmingly against then it would be folly to appoint him.
Lerner will have to take a shot gun approach now and ask to speak to Moyes, Coyle and Martinez, with the hope of getting one of them. I take it that van Gaal and Rijkaard aren't on the radar.
