4- Jurgen Klopp
A man who was tipped for the United job, but no negotiations ever materialised.
Klopp's tenure in the higher echelons of football management has so far been a marked success, transforming a young Borussia Dortmund into a team capable of challenging even the very best of sides.
The German's tactics and eye for picking up young talent, coupled with his confidence to then field that talent consistently has earned him a healthy reputation around Europe, and it will be a surprise if one of the biggest clubs don't try and prise him away eventually.
United you feel had the chance to do just that, and my guess is that Klopp would have relished the chance to challenge himself at the helm of the Premier League rivals, but they opted for Moyes instead.
Once again, Klopp's brilliant relationship with his players means that one or two would have probably followed him to England had he left.
