I think he's wrong to try and take on the Man United fans and to have a little dig in the programme.
Although United won the last fixture against Chelsea at Old Trafford in April, Mourinho witnessed his team get humiliated by a 4-0 score-line at Stamford Bridge this time previous year, as well as crashing out of the FA Cup in west London as well.
Lukaku has gone six games without a goal after starting his Manchester United career with 11 in his first 10 appearances.
Lukaku's barren spell has seen him questioned by some supporters, along with United's displays as a whole, leading Mourinho to enter into a war of words.
"The fluidity of the team is not the same as it was at the start of the season without Pogba".
"When Mourinho makes a change, he's doing it for the right reasons, and because he's one of the best in the world".
He admits that Manchester United's legacy is based on flamboyant football but stressed that Mourinho is doing the job he was brought to do - to get the club to win trophies again.
The 11-time Premier League title victor added on United's class of 2017-18: "They're in a position where they've brought a manager in to ultimately win the league".
This has drastically affected Romelu Lukaku's game as well as form, as it has majorly subdued the service he receives, and he often has to come very deep in order to just get a touch on the ball. Not one United fan was moaning.
"Now, he hasn't scored in a few games and suddenly loads of fans are on his back".
"We scored two goals, did not concede, gained three more points, more money for the club because every victory means money and did not have any significant injuries".
'Matic is a great signing: he knows the game, he's got great experience, he's got presence about him and he gets in the right areas at the right time. Those fans needed telling.
