24-year old Romelu Lukaku scored his third goal of the season-and the second of the match, essentially sealing the outcome and three points for good.
But Mourinho has made a decision to shake up the preparations before Old Trafford matches in an effort to help performances on the pitch.
If early results could be representative of the whole campaign, United would have to fail catastrophically to finish outside of top four.
United's ominous start to the season has been partly down to Pogba's impressive performances: Scoring in the first two games, against West Ham and Swansea, as well as adding an assist.
Martin Fisher: "Six points, eight goals scored and none conceded". Mahrez, who looked superb against Brighton, has registered three assists already.
But it is another example of how Mourinho is gradually stamping his own authority on the way United as a club is run in his second season in the job. With two clean sheets in as many games, it is the attack that has stolen the headlines.
-United now sit atop the Premier League table with six points, and a +8 goal differential, up four on Huddersfield.
One thing United lacked last season was the inability of their key men to deliver consistently last season, but as evidenced against the Hammers and the Swans, the Red Devils have put that issue behind them.
In last year's Champions League, Spurs flamed out in the group stage, Arsenal and Manchester City were shellacked in the round of 16 and only plucky little Leicester could soldier on to the quarterfinals before running out of steam. Having scored twice and assisting twice, along with the four assists registed by Mkhitaryan, the unsafe pair have contributed to eight goals combined. Off the pitch, he's become the club's poster boy and his positive, fun-loving attitude has rubbed off on other players like Jesse Lingard, Marcus Rashford and even perennial non-smiler Anthony Martial. Aside from that 4-1 win at home, they also defeated them 2-1 in the 2016 Community Shield, and 3-0 at King Power Stadium.
After somehow scraping a 4-3 win in their opening game against Leicester, Arsenal went down to a disappointing (if somewhat predictable) 1-0 defeat to Stoke City last weekend.
The Foxes have lost seven of their last ten away league fixtures. Under the guidance of Craig Shakespeare, the Foxes registered away victories to West Ham and West Brom.
Arsene Wenger's side finished outside the top four of the Premier League for the first time since 1995/96 last term and the French star will be expected to fire them back into the Champions League spots this season. Doubts about that decision would have been understandable during his early days at Old Trafford and especially when he was abruptly substituted at half-time vs. City, having been outplayed by Kevin De Bruyne.
