Albion fought back to stun 10-man City with an astonishing 3-2 victory as Dan Burn swept home a 76th-minute winner against Pep Guardiola’s shocked champions.
An early header from Ilkay Gundogan and a superb individual effort from Phil Foden just after the restart put City in control before Albion came roaring back courtesy of substitute Leo Trossard and defender Adam Webster.
City played for 80 minutes a man down after Joao Cancelo was dismissed for denying Danny Welbeck a goalscoring opportunity.

9. Jakub Moder 7/10
A very athletic display from the Poland international who looks to be a player of great promise. Currently playing out of position on the left and he will be even better next season
10. Alexis Mac Aliister 6/10
Selected ahead of Trossard and worked hard and clever on the ball in midfield. A very determined player who tracked City's midfielders.
11. Danny Welbeck 6/10
The major downside of the evening was the hamstring injury to Danny Welbeck. Looked lively early on and it was his run that saw Cancelo sent off.
12. Leo Trossard 8/10
Made a huge impact after coming on to replace Welbeck on 29 minutes. Tricky on the ball and a great strike to haul Brighton back into the match. Well played!
