Former Manchester United midfielder Ron Atkinson says Jose Mourinho's us-against-the-world approach won't work at Old Trafford.
Mourinho's United have lost three matches in eight days, including a home derby defeat to Manchester City and a shocking 3-1 loss at Watford on Sunday.
The Portuguese, who known to create outside enemies in hopes of creating a bunker mentality within his teams, was harshly critical of referee Michael Oliver after his side's loss at Vicarage Road. However Atkinson says the former Chelsea and Real Madrid boss must find another tactic with the Red Devils.
"I have never been a huge fan of this siege mentality he brings to his clubs," Atkinson said.
