#4 Pogba and Martial's newfound confidence and roles
Martial did well to get beyond Brighton defenders, though himself and Pogba were both disappointing in-front of goal.
Duffy made an important intervention to thwart the winger with an excellently-timed sliding tackle, while he also had a goalbound effort stopped in his tracks during a bright first-half display.
In 24 appearances this term (all comps), Martial has netted nine goals and created one more. He's capable of more and naturally performances like these will provide him - as well as the United faithful - with confidence that he'll continue to develop at a steady rate.
News of a new extension deal being tabled isn't much of a surprise, given the uncertainty behind his long-term future under Jose and how he's got 18 months left on his existing contract. If anything, it provides an extra incentive for him to perform and retain his starting berth, which is easier said than done.
Pogba, whose attitude has been questioned in the aftermath of Jose Mourinho's sacking last month, has scored five goals and created four more since the Portuguese's departure.
He's playing with confidence in a free-roam attacking role ahead of Ander Herrera and Nemanja Matic where he's given the license to roam forward as he pleases but equally does more pressing when out of possession.
Came close with an overhead kick and clearly has the confidence to be trying these audacious moves. As long as his performances remain consistent, questions will not be asked in that regard.
It's not something you always saw under Jose's tenure but with expectations heightened, it'll be interesting to see how he progresses as United have tougher fixtures to come. The standout one is their Champions League tie against Ligue 1 champions Paris Saint-Germain next month.
