The two talented strikers have both been utilised solely on the left-wing so far this season, but five games in, both are looking confident and exciting.
José Mourinho has managed to balance the talents of both by rotating Rashford and Martial with regularity over the course of the season.
Speaking to MUTV, Rashford said that it is “difficult when you’re in and out of the team, but we have to find the positives out of it and I think we have both [he and Martial] done that.
“I think the competition is always positive competition because we’re improving each other every day when we’re in training, and in the games, we’re pushing each other more and more.”
Rashford, 19, and Martial, 21, have responded to the difficulties superbly. Their attitude is exemplary, never complaining when being subbed off for the other, and working harder than ever when they have been brought on for the other.
With that, Mourinho has two fantastic options.
“It’s a bit of a headache for the manager, but it is a good headache to have,” Rashford said.
Rashford continued his stunning record of goalscoring debuts on Tuesday night with a goal off the bench in Man United’s 3-0 win against FC Basel.
Martial had a quiet game, but caused some trouble to a deep-lying defence at times. The Frenchman had a tricky 2016/17 season, with questions over his attitude and workrate, but has come back from the summer looking like the Martial that United fans saw when he first arrived as a teenager in 2015.
The question going forward is whether Martial and Rashford will ever regularly start together for United. At this stage, it’s fine for the answer to be no, given their respective ages. But in a few years, their abilities will be such that it will be hard to not at least attempt to fit both of them into the side.
Mourinho has rarely done so yet as United manager, playing the two together just nine times in 70 games at the helm.
