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".
Surprisingly, the United boss seems most put out by an apparent lack of support for Romelu Lukaku against Spurs, saying it was unfair that fans "don't support him so much" and that they should view him as "untouchable" like he does.
Mourinho's unexplained chatting hand gesture after Daley Blind wrapped up a 2-0 win against Benfica from a penalty that he took Lukaku off further muddied the water, with MUST keen to speak to the manager about his concerns over the United support.
United take on Chelsea on Sunday but they are not back in action on home soil until November 18, when Newcastle visit in the late Premier League kick-off.
Mourinho has regularly spoken about the Old Trafford atmosphere since joining the club, but player support is a new issue.
The United boss did, though, offer an insight into the seemingly current fragile nature of Lukaku's confidence after preventing him from taking Tuesday's penalty.
Mourinho's men rode their luck after taking the lead against Benfica through Mile Svilar's own goal, with Blind told to take the spot-kick that wrapped up a 2-0 win rather than Lukaku - now without a club goal since September 30.
