According to BBC Sport, United are set to appoint former Chelsea boss Mourinho as their new manager.
Former Tottenham chairman Lord Sugar has suggested on Twitter that Mourinho would not be a good managerial appointment for United.
When things were going wrong for LVG. Mourinho started to play up at Chelsea to get the sack. Let's see if he is the special one at Man U— Lord Sugar (@Lord_Sugar) May 22, 2016
.@ManUtd will need a big cheque book with Mourinho ,it's the only way he knows how to succeed . He could/will never do a Leicester.— Lord Sugar (@Lord_Sugar) May 22, 2016
I am willing to say Man U won't win the PL next season https://t.co/kWffHeZ3U5— Lord Sugar (@Lord_Sugar) May 22, 2016
@Lord_Sugar he'll win trophies there that's almost guaranteed but will his personality let him get past 3 seasons before he implodes?— Jeff (@Bravo24Charlie) May 22, 2016
He will not win the PL or the CL at Man U https://t.co/Xc2v4UE7ma— Lord Sugar (@Lord_Sugar) May 22, 2016
Mourinho has been without a managerial job since December 2015 when he parted company with Chelsea following a run of disappointing results in the Premier League.
The Portuguese guided the Blues to the Premier League title during the 2014-15 campaign, and is a very good football manager.
