The Scot is the longest serving manager in the history of the Red Devils and has been in charge at Old Trafford since 1986, winning 12 Premier League titles, five FA Cups, four League Cups, one European Cup Winners' Cup and two Champions League trophies in the process.

In contrast, the Roman Abramovich era - despite the success achieved - has seen the Blues undergo seven managerial changes in eight years.
""It is hard to explain why it is the way it is at Chelsea sometimes,"" Cech told The Sun.
""But now we have a young manager who can hopefully stay for 25 years like Ferguson at Manchester United.
""It would be great to have that continuity here.""
The Czech shot-stopper feels that the Portuguese boss' prior experience at Stamford Bridge as assistant to Jose Mourinho, coupled with his success in leading Porto to Europa League glory last season, make him a positive appointment.
""Andre is a great choice. He is young and he has proved that he can manage a big club to success. He knows English football and he knows our club - that will be a massive help,"" added Cech.
""We know him and he knows us from the time when he was here with Jose Mourinho. Andre did a fantastic job then with all his analysis of our opponents which I always found a big, big help.
""And I'm sure he will do a fantastic job again.""
