Brighton vs Manchester United live updates: Mac Allister penalty ...

Manchester United deserved that result for their second-half performance. They didn’t show up after the interval.

Shaw had been pretty faultless until that unnecessary handball.

United’s awful away record against the top 10 continues. Seven losses, one draw, one (last-minute) win.

Brighton jump up two spots to sixth place. Fifth place is well within reach for Roberto De Zerbi's men.

Manchester United stay in fourth place, failing to overtake Newcastle for third as well as missing an opportunity to consolidate their Champions League hopes.
