The 52-year-old was sacked by Chelsea on Thursday but the negative assessment of his character by senior Old Trafford figures in the past could rule him out of a job in the future.

Having now been sacked by Chelsea for a second time, many are immediately pointing the 52-year-old in the direction of Old Trafford once more. As United’s struggles under Louis van Gaal intensify, the availability of one of the accepted greats of modern management will only make life tougher for the Dutchman.
