David de Gea
Denied Teemu Pukki in a one-on-one at 0-0 that was pivotal and made another fine save when Milot Rashica went for goal. 7
Diogo Dalot
Eager but not strong enough in the challenge for Kieran Dowell's goal. Made a couple of key blocks in the second-half at 2-2 and 3-2. 6
Victor Lindelof
Made a crucial intervention late in the first-half only to be let down by teammates soon after when Norwich scored and he played Pukki onside. 5

Harry Maguire
Lacked authority in a porous defence again as Norwich created good chances in both halves and United's defence was all over the place. 5
Alex Telles
Assisted Cristiano Ronaldo direct from a corner but switched off to leave Dowell unmarked and was jogging in the second-half. An embarrassment. 4
Paul Pogba
With the sun out and the league's worst team in town, Pogba thrived in the first-half but when the going got tough he went cold. Cheered off, booed off and told to 'f--k off'. 4
Jesse Lingard
Bright as an attacking midfielder in a three, a role he has not played in enough for United. A goal threat at times yet oddly withdrawn. 7
Bruno Fernandes
A familiar performance of commitment but little quality and he was lucky not to come off when Lingard did. Got worse since his contract renewal. 4
Anthony Elanga
Seized on Ben Gibson's dithering defending to tee up Ronaldo for the first goal and offered so much energy he switched to right-back. 6
Jadon Sancho
Had enough of the ball but did very little with it despite returning to his favoured left-hand side role. Switched to the right to accommodate Marcus Rashford. 5
Cristiano Ronaldo
Scored clinically twice in the first-half to take his club tally for the season to 20. Then claimed another hat-trick with a free-kick. 9
Subs
Nemanja Matic
Had another positive impact off the bench. 7
Juan Mata
Had a shot blocked. 6
Marcus Rashford
Had few opportunities. 5
Manager
The front six was too loose and that wasn't a problem with United winning. Rangnick reacted well to introduce Matic and hook Pogba. 6
