However, Kieran Dowell’s goal out of nowhere in first-half stoppage time got the visitors back in the contest, before Finnish forward Teemu Pukki completed the Norwich comeback to stun Old Trafford into silence seven minutes after the break.
Fans who protested against the club’s owners ahead of the match were singing “you’re not fit to wear the shirt” in the second half as their team were second best to a team seven points adrift of the Premier League safety zone.
United’s France midfielder Paul Pogba was booed by his own fans as he was substituted before Ronaldo stole the show once again with a sensational winner 14 minutes from time to drag United out of the mire once more.
The win, United’s first in four games in all competitions, moved them above Arsenal, who lost 1-0 at Southampton, into fifth on 54 points from 32 matches, with Spurs now just three points in front. Norwich stay bottom on 21 points
