Mainoo’s brilliant run and curled finish ensured United began February in winning fashion, at the very end of a rollercoaster meeting at Molineux.
Erik ten Hag’s side seemed to be cruising to victory when 3-1 up with five minutes to play, after Scott McTominay had headed home with virtually his first touch after coming on as a substitute.
But Max Kilman bundled in to halve the deficit and Pedro Neto hit us on the counter to draw the home side level in added time, to seemingly leave the Reds ruing two dropped points.
There was another twist in the tale, however, and it came courtesy of 18-year-old Mainoo, who opened his top-flight account in the grand manner.
