Kevin de Bruyne only started 11 Premier League matches in 2018/19 while Riyad Mahrez struggled to break into the first team in his debut campaign at the Etihad, meaning their partnership down the right is a brand new weapon for Pep Guardiola; the Belgian has taken to regularly drifting out to the right flank, dominating against Liverpool at Wembley before an equally assured performance at London Stadium on Saturday.
Despite an attacking, impressive performance in the first half at Old Trafford, Chelsea went into the break 1-down to Man United.
Mourinho, who is now working as a pundit, was impressed with some of United's players on Sunday, but reserved special praise for new signings Harry Maguire, Aaron Wan-Bissaka and Daniel James. "With Maguire it can be a very good partnership".
James made it a day to remember by adding his side's fourth goal just nine minutes after coming on as a substitute in his competitive debut.
Lampard's first team selection was a bold one as he put his faith in youth with Tammy Abraham and Mason Mount handed starts, while £60 million signing Christian Pulisic was made to wait for his Premier League debut on the bench. David Luiz has been sold, N'Golo Kante didn't start due to injury and Antonio Rudiger is still out, so this Chelsea defensive unit will look a lot different when it is fully fit. Kurt Zouma and Andreas Christensen have both showed their quality plenty of times before, but both looks nervous and uncomfortable imposing themselves on a game or on their fellow defenders in the way you want a centre back to.
"He lost it a couple of times but it doesn't matter - get on the ball and play". Just two minutes after Martial's goal, Rashford got his second off a spectacular ball from Paul Pogba.
Nevertheless quick breakaways will become a defining feature of the club under Solskjaer, with goals like James's a frequent occurrence whenever the opposition tires or begins chasing the game.
We saw the best and worst of Pogba on Sunday and that is the main problem. Romelu Lukaku is now at Inter Milan, and United is really without a true No. 9.
Chelsea's all-time record goal-scorer had been immediately hindered on his appointment last month by the club's transfer ban over the summer - a factor the former England midfielder highlighted.
