Manchester United mark a big anniversary later this week: It's 40 years since they last made the right decision on a managerial appointment.

They have become the club that always gets it wrong. Jürgen Klopp, Mauricio Pochettino and Thomas Tuchel have all spoken to the United hierarchy in recent years. But for one reason or another, they have all taken their coaching talents elsewhere.

As current boss Michael Carrick lurches from one bad result to another and with United hovering one place above the Premier League relegation zone having won just once in the league all season, Friday's anniversary of Alex Ferguson's arrival at Old Trafford in November 1986 might just coincide with the club's latest roll of the managerial dice.
