Manchester United lost 2-1 away at Brighton in their first Premier League away match of the new season.
Erik ten Hag made no changes from the side that defeated Fulham on opening night, which meant summer signings Joshua Zirkzee and Matthijs de Ligt remained on the bench from the start. Jadon Sancho did travel to the AMEX Stadium but wasn't named in the 20-man squad.
It was another step in right direction from a performance perspective, with United much improved in their pressing play against a Brighton side who are notorious for a similar tactical approach.
United started as the better side without creating too many chances and were made to pay when Danny Welbeck gave the home side the lead against his former club after some poor defending from Harry Maguire and Noussair Mazraoui.
Joshua Zirkzee replaced Mason Mount at the break but it was Brighton who began the better side after the restart as United began to look stretched.
Welbeck twice had the chance to double the lead for his side with headed efforts, while Diogo Dalot made an important goal line clearance to deny James Milner a goal.
They proved to be costly misses when Amad levelled the scores on the hour mark with a deflected effort after he cut inside from the right wing.
United were much improved following the equaliser and almost took the lead when substitute Alejandro Garnacho finished a brilliant counter-attack, only for it to be correctly ruled out for offside.
Ten Hag's side looked on course to hold on for a point before Joao Pedro headed in the winner in the fifth minute of added time after some dreadful defending.
Here is how we rated the United players in the match:
9. Bruno Fernandes - 6
Fernandes worked well out of possession but did little to influence the game for his side. Would have had an assist if not for Zirkzee's intervention on the line. | Getty Images Photo: Getty Images
10. Amad Diallo - 8
He contributed well to the pressing play. Should have done better when Dalot set-up him up in the first-half but was at the heart of most things his side did well and deserved his goal. | Getty Images Photo: Getty Images
11. Marcus Rashford - 5
Was guilty of straying into offside positions far too often but looked bright at times. Worked hard but few complaints when he was replaced. | Getty Images Photo: Getty Images
12. Joshua Zirkzee - 6
A few nice pieces of link-up play but could perhaps have done more in the box. Will be interesting to see how United get the best from him. Unfortunate with the disallowed goal. | Manchester United via Getty Images Photo: Manchester United via Getty Images
