"There are a lot of individual qualities in the players around him [at United]".
The defender also added that Everton have never given Manchester United an easy game since the time he has been at Old Trafford.
And Mourinho expects the United faithful to recognise his achievements - but just hopes they don't give him too much encouragement during the game.
Mourinho went on to declare he was happy with the squad he has assembled at United and he believes the relationship between the club's supporters and their team has changed for the better.
Pogba was withdrawn after 19 minutes during United's 3-0 win over Basel in their Champions League opener on Tuesday night (12 September) and now faces up to six weeks on the sidelines with a hamstring injury.
"They're waiting for a real chance to start matches and to play from the beginning". Mourinho has used Matic, and the former Juventus man in the central midfield position this season.
Wayne Rooney makes a return to his old stomping ground as Everton visit Old Trafford and ex-player Phil Neville has warned Manchester United that their former captain will be desperate to score for the Toffees on Sunday.
"They had a great game in the Champions League in the week and fought hard against Stoke last weekend".
"Of course, especially for a striker, it's important how many goals you score", said Mourinho.
"The way the team plays I think they have to, when a team doesn't create a lot, doesn't have the ball, when it's just a reactive team, it's more hard".
"We know him really well", Koeman said of Lukaku.
Rooney has taken a locker in that particular room at club level on just two previous occasions, the most recent of which was the aforementioned outing on Boxing Day 2003.
He said: "I am not going to compare".
Paul Pogba's injury would be a big blow to United with the 24-year-old finally showing signs why United forked out £89 million for his signature last summer from Juventus.
Everton manager Ronald Koeman revealed he would hold a meeting with his senior players to try to get their season back on track before the trip to Old Trafford.
