A devastating first-half blitz from Brighton secured a memorable 3-2 victory over Manchester United on Renault Super Sunday.
There was sheer jubilation inside the Amex Stadium as two goals in two minutes from Glenn Murray and Shane Duffy put Brighton two up inside 27 minutes.
Romelu Lukaku halved the deficit on 34 minutes with a close-range header but there was no respite for the beleaguered United defence as Pascal Gross won and converted a penalty on the stroke of half-time to put Brighton in control.
Paul Pogba scored a penalty in stoppage-time but it came too late to inspire a comeback as Jose Mourinho, in the week in which he accused Manchester City of lacking class, was left to reflect on a gulf in class on the field.
Brighton lost captain Lewis Dunk to injury after an even opening 21 minutes, but rather than handing United the opportunity to expose any defensive weaknesses, the Seagulls went on the attack to devastating effect.
After Anthony Knockaert dragged a shot wide, Solly March drilled a cross into the United area where Murray nipped ahead of his marker to deftly chip his first goal of the season beyond David de Gea.
Brighton celebrations turned to pandemonium two minutes later as United failed to clear their lines from a corner on no more than three occasions, allowing Duffy time to rifle a quick-fire second.
United were shell-shocked and bereft of ideas until a cross under pressure from Luke Shaw found Lukaku in space in between the advancing Brighton centre-backs, and the Belgium international nodded home from close range.
But the momentum was soon back in Brighton’s possession as a needless Eric Bailly lunge on Gross, who was going away from goal, handed Brighton a penalty, which the German dispatched through the legs of De Gea.
Mourinho brought Jesse Lingard and Marcus Rashford on at the break, and Marouane Fellaini on the hour, in a bid to inject some life into his struggling side.
United improved slightly but took an age to test Maty Ryan, Pogba’s curling shot from the edge of the area drawing the Brighton goalkeeper into action 16 minutes from time.
And by the time Pogba had converted a penalty deep into stoppage-time, after Duffy had brought Fellaini down, it was too little too late as Brighton basked in another memorable victory.
