England started slowly and the Red Devils had already had a goal disallowed when Romelu Lukaku put them ahead from the spot with a quarter-of-an-hour played.
But England responded with a penalty of their own to ensure they went in level at the break. This time Jordan Henderson was tugged back attacking a corner, and with no Harry Kane on the pitch, it was left to Rashford to finish emphatically from 12 yards.
Roberto Martinez’s side had certainly had the better of the opening 45 minutes, but England improved when play restarted, showing greater urgency in possession.
On a couple of occasions, they were able to make better use of the areas Mount was finding on the right-hand side, with one such attack ending in a Trent Alexander-Arnold effort being deflected just wide.
Mount soon switched to the left and on 64 minutes found a pocket of space from which he gave England the lead. Collecting a Kieran Tripper nod-down just inside the box, he cut inside and curled goalwards. The shot took a deflection off Toby Alderweireld, and looped over Simon Mignolet and into the top right-hand corner.
