Mason Greenwood completed Manchester United's spirited second-half fightback as they came from behind to beat Brighton 2-1 at Old Trafford
Danny Welbeck headed the Seagulls into a deserved lead against his former club (13) with a lacklustre United having failed to register a single shot on target in the opening 45 minutes
But Marcus Rashford restored parity with his 19th goal of the season (62) before Greenwood stooped to head in Paul Pogba's mis-hit as Brighton's resolve was broken with seven minutes remaining
The result comes as a relief for Ole Gunnar Solskjaer, whose side stay second on 60 points - meaning Manchester City still require a further 11 to be confirmed as champions
 Brighton stay 16th, six points clear of the relegation zone
Brighton were seeking to win three consecutive Premier League games for the first time since October 2018, and Graham Potter stuck with the same team that dismantled Newcastle in their previous fixture before the international break
United welcomed back Edinson Cavani, and they came close to breaking the deadlock inside nine minutes when Bruno Fernandes' cross was headed out only as far as Mason Greenwood but his low shot struck Robert Sanchez's left-hand post
United had won five successive meetings with the Seagulls but that was as good as it got for Ole Gunnar Solskjaer's men in the first half as the visitors began to assert themselves - and they edged in front four minutes later
Pogba's slack pass inside to Fred was gobbled up by Pascal Gross as Neal Maupay was sent on his way down the right channel
 Luke Shaw gave the forward too much time to shape a cross that was met by Welbeck, forcing a smart save with the legs from Henderson but the ball looped back up and was headed over the line at the second attempt
In doing so, Welbeck became the first player to score as many as three Premier League goals against United after leaving the club
If Solskjaer expected an immediate response, he didn't receive it
 Instead, Potter continued to encourage his players forward and Brighton were unfortunate not to double their lead when Henderson showed sharp reflexes to tip over Lewis Dunk's header from a Gross free-kick
The Seagulls sniped time and again in the opening period, with Pogba and Fernandes both guilty of giving the ball away regularly - and Henderson was fortunate when he spilled another Gross set-piece having collided with Harry Maguire
"It seems ridiculous this Brighton team were involved in a relegation battle six-pointer last time out," Sky Sports' Peter Smith commented at the break
 "They've gone toe-to-toe with the second-placed team in the league, away from home, and looked the better side so far tonight
"The potential of this team is far beyond their current league standing
"United had failed to have a shot on target in the first half of a Premier League game at Old Trafford for the first time since August 2019 against Crystal Palace - but they finally tested Sanchez when Rashford collected Maguire's pass seven minutes into the re-start but the long-range effort was straight at the Brighton stopper
There was more intent about Solskjaer's side, with Scott McTominay intensifying his warm-up on the touchline appearing to have the desired effect
 On the hour-mark, Sanchez came haring off his line to smother Fernandes' shot from Pogba's through-ball - but the reprieve for Brighton was short-lived
Joel Veltman lost possession and clattered into Fernandes as he sought to atone for his error, but referee Mike Dean waved on the advantage as the Portuguese had found Rashford to his left and the forward swept home the equaliser with a precise, first-time finish
Brighton still posed a threat on the counter and there were penalty claims when Welbeck was unable to reach Maupay's low cross, feeling a tug from Maguire but VAR Peter Bankes stuck with Dean's on-field decision of a goal-kick
United nearly took full advantage of the let-off
 Sanchez's save from Fernandes' speculative drive fell straight to James, who squared for Greenwood, but the teenager's shot on the stretch just cleared the crossbar
The miss didn't play on his mind, however, as with seven minutes remaining, Greenwood was in the right place to head in Pogba's miscued shot despite Ben White's best efforts on the goal line
 It was cruel on Brighton but United had dug in
Manchester United boss  told the : "It's always difficult to play Brighton
 We have had good results and we've had to earn them the hard way
 We managed to find a way in the second half
"Danny [Welbeck] was in the reserves when I was the coach
 He is a big talent
 It's great to see him back playing football with all the injuries he has had
 We gave it away sloppily [for his goal]
 Dean [Henderson] makes a good save first but then the rebound comes in
 We had to come in at half time and compose ourselves as we didn't create much after they scored
"I thought we started well but when they scored, after that we couldn't find our rhythm again and we needed half-time to compose ourselves and go again
 Second half we played some good stuff
 More runs in behind, more movement, better movement
"Sometimes after international breaks it takes time - and then maybe the fireworks have to be lit at half-time
 Mason Greenwood needs to add those goals to his tally because we know how wonderful a talent he is, and when he can add those goals we know he'll be a good'un
"Brighton boss  told the : "We contributed well in the game
 We took the lead and were probably the team which carried the most threat in the first half
 We just missed that final pass
 Man Utd responded in the second half without creating too many chances
 They scored from not too much
 Maybe a penalty which Danny Welbeck didn't get
"When it was life I thought it was a penalty then I suppose it's the clear and obvious debate
 If Mike Dean had given it I don't think VAR would have overruled it
 There's nothing we can do in the end
 We're disappointed to come away with nothing
"I'm confident in terms of the team, the way we're playing and the personality in the team but until you get the points you can never relax
 Sometimes the opposition have some quality that you have to hold your hands up to and say 'that's good
' We'll keep going
"Even during off days, Fernandes can be so lethal
 He was subdued for large parts of the first half, but as Brighton faded, United's talisman came to the fore
 Fernandes provided four key passes, more than any other player while he also had the most number of shots (3)
He might have sulked and stropped after being clattered into by Veltman having provided the assist for Rashford's equaliser, but instead he clicked into gear and was involved in the match-winner, setting up Pogba whose dragged shot fell kindly for Greenwood
Fernandes has been directly involved in five goals in three Premier League appearances against Brighton (3 goals, 2 assists)
 Fernandes has been involved in more Premier League goals since his debut than anyone else (42 - 24 goals, 18 assists)
"It was a hard night
 When they scored the first goal we knew we had to react and put in a better performance
 Everyone was excellent in the second half
"I don't think we started very well but we knew we had to switch on and be focused
 We should have started that from the moment we came out, but it's a good three points
 There was a lot of men behind the ball and we had to have that creative spark
"It's a confidence booster, I've not scored as many in the Premier League
 I scored a header tonight which is something I've been working on a lot behind the scenes
"Manchester United travel to face Granada in the Europa League quarter-final first leg on Thursday; kick-off is at 8pm
