Rodgers or Martinez would be ideal to build something, not going to happen though, obviously wouldn't want Rodgers to happen either.
Hes different to those 2 but out of realistic targets that could be persuaded then Benitez would be very high on the list, it was a big opportunity missed not to let him have a shot at the 2012 Euro's with England imo.
Hes a knock out football specialist, a top tactician and actually knows what hes doing, at least the team would be organised and everyone would know exactly what their jobs are with and without the ball, England would certainly have more of a chance of doing something of note with him in charge than the current buffoon.
