Martial has featured less than his counterpart, making just four starts in total, but has claimed a superb five goals and four assists during what has been a lethal start to his second season under Jose Mourinho.
And Rashford has likewise claimed five goals, including his first in the Champions League, while clocking two assists from six starts.
Speaking earlier this week, Young noted that the pair will spur each other on by fighting for a spot in the staring XI.
“It is a team game and a squad game and everybody wants to be playing well and wants to be in the team,” he said.
“Everyone is fighting for places and it is healthy competition. Like I’ve said all along, you have 20-plus players all wanting to get in that starting XI.
“You see the way training is – it’s fast, there’s aggression there, everyone wants to win, everyone’s got a winning mentality, you take that into games and we’ve shown that this season.”
Very rarely does a manager stumble upon such a powerful dynamic in one position – an ability to unleash fresh, penetrative talent on a weekly basis, changing between the two in accordance with the situation.
They offer slightly different styles: Rashford brings more thrust and power while Martial has an element of slickness to his play. And yet, at the same time, they share one defining characteristic: a capacity to place opponents on the back foot – something supporters haven’t seen too often over the last few years.
