Jose Mourinho spent almost £150 million this summer on Eric Bailly, Paul Pogba and Henrikh Mkhitaryan - while he also captured Zlatan Ibrahimovic on a free transfer.
United supporters have had the pleasure of watching Bailly, Pogba and Ibrahimovic settle into the squad but Mkhitaryan has been a bit-part figure during the opening few weeks.
Well, that was until Mourinho gave him the nod to start the Manchester derby. The Armenian was given his first start last weekend in the biggest match of the season so far at Old Trafford but things didn’t exactly go to plan.
The former Borussia Dortmund star was hauled off at half-time during the 2-1 loss following a fairly anonymous display and one that appeared to anger his boss.
Mourinho on Mkhitaryan
"I'm clearly disappointed with the first-half," Mourinho said after the match.
"Disappointed with some really poor individual performances that affected the level of the team.
“We didn't have a tactical problem, we had problems with poor performances, we lost the ball very, very easy.
"I made a couple of decisions that I thought individual qualities of certain players would give me what I know that I want and I didn't get it.
"I didn't change after 20 minutes because I don't want to destroy the players.”
So, it’s obvious that the Special One wasn’t too pleased with Mkhitaryan.
But it seems the feeling is mutual. According to The Sun, the midfielder is unhappy with Mourinho because of his insistence to play him out of position.
The report claims that the £30 million signing doesn’t want to play wide right in a three behind the striker, a position he has featured in all of his appearances so far.
Mkhitaryan showed his incredible ability last season in the Bundesliga, scoring 11 goals and providing a further 15 while playing as a number 10.
However, if Mkhitaryan wants to operate in that role for the Red Devils, it would mean Mourinho would have to drop his captain, Wayne Rooney.
It’s certainly not something you want from your summer signing to be complaining about the role he is playing after just a few weeks. Surely things like this are discussed before you sign a contract at the club you’re signing for?
And it's unlikely that he will be able to right his wrongs against Feyenoord in the Europa League on Thursday with The Sun reporting that the Portuguese boss is set to punish both Lingard and Mkhitaryan by starting them on the bench against their Dutch opponents.
