Jose Mourinho has been invited to 'discuss his concerns' around the Old Trafford atmosphere by the Manchester United Supporters Trust.
Apparent tension between the manager and sections of the fan base has been a hot topic since the Portuguese held a finger to his lips and told the doubters to calm down after beating Tottenham on Saturday.
Those actions were fuelled in the build-up to Tuesday's Champions League win against Benfica by Mourinho writing in the programme notes to supporters that he hoped they 'enjoy the game more than some of you did against Tottenham'.
