Manchester United brought the much-needed determination to the Premier League campaign by defeating Brighton in one afternoon, as Marcus Rashford rose from the sublime to the ridiculous.

The mood at Old Trafford was optimistic this time after unpleasant questions surfaced in the previous international break following a shock in Newcastle.

Ole Gunnar Solskjaer's team are in seventh place after beating Brighton 3-1. Andreas Pereira and Davy Propper's own goal made United move towards a win Rashford scored for Lewis Dunk.

The beating of the English striker from the bottom of the bar provided a good overall picture, although the 22-year-old does not want to see his inexplicable shot from close range.

However, Rashford's confidence did not seem to be affected as Brighton's goal was besieged by United's fourth Premier League victory.

Albion never looked to win his first win at Old Trafford, where Scott McTominay's injury later gave cause for concern.

It was a better afternoon for academy colleague Brandon Williams, who celebrated standing ovations after his first start in the Premier League.

United showed little signs of fatigue after beating Partizan Belgrade on Thursday and unsettled the normally reliable Albion defense from the start.

Rashford was not able to keep up an excellent, clean run with the hosts clear in the first shot, but Solskjær's side made a breakthrough in the 17th minute.

Victor Lindelof and Fred were involved in a train in which Andreas Pereira raced through the middle.

Dale Stephens & # 39; Zweikampf seemed to have finished the attack, only that the ball had fallen for Martial and the Frenchman had to cut back the Brazilian after a hit by the unfortunate midfielder Albion.

It would get worse for Graham Potter's men soon after Dunk was booked for a late, awkward challenge to Daniel James. Fred performed well after the free-kick, causing Propper to drive the McTominay attack across the line.

The VAR checked the involvement of Harry Maguire and 140 seconds after the ball crossed the line, Old Trafford could celebrate fully.

It was a rare United free-kick against an Albion team that looked more threatening dead balls.

Martial saw that a handball objection was denied and Pereira was rejected from a distance when United returned sharply after the break, but there were a few nervous moments when the stadium announcer confirmed that the VAR was looking for a red card.

Teenage Williams and his teammates were relieved to see his high foot on Steven Azalte remain a booking.

The Brighton goalkeeper, Mathew Ryan, was relieved to miss a shot from Fred who bounced off the crossbar – a break that Brighton used when Pascal Gross swung over a corner, the dunking too easily could hit a dull blow head home.

But instead of fighting back, United recovered and restored his two-goal cushion within two minutes.

Fred's pass brought Martial behind the back of Brighton and the Frenchman kept his cool as he was forced to keep playing so Rashford hit home from the bottom of the bar.

Only the striker from England will know that he has not scored a quick second goal. James lunged to the right and sent a low cross to Rashford, who inexplicably shot far off the far post, leaving the gate at his mercy.

It was a notable mistake, but United was not deterred when Williams and James made quick attempts before Rashford followed with a shot from Ryan on the post.

Martial and Rashford were both close aside when McTomay came down after injury on a stretcher.
