2. Mauricio Pochettino
Tottenham manager Pochettino has been on United’s radar ever since he lunched with Ferguson at a Mayfair restaurant in 2016. Not winning any trophies has been the stick to beat 46-year-old Pochettino with during his time in north London. But the Argentinian plays bright, attacking football and was high on United’s list of targets to replace Louis van Gaal. Influential figures at Old Trafford are said to be big fans of Pochettino, who throughout his career has blooded young players in the United way. But prizing him away from Spurs chairman Daniel Levy would prove extremely difficult, if not impossible.
