PREM: Man Utd 3-2 Newcastle

Paul Pogba and Chris Smalling react after Newcastle's second goal

An under-pressure Jose Mourinho saw his Manchester United side fight back from two goals down to earn a dramatic 3-2 win against Newcastle at Old Trafford on Saturday.

Substitute Alexis Sanchez grabbed the winner with a dramatic 90th-minute header, giving the hosts what had seemed like an unlikely victory and sending Old Trafford wild.

The pre-match talk was dominated by Mourinho's future, with Man Utd insisting they will remain patient with their manager, dismissing reports he would be sacked after the game.

But the talk intensified as Mourinho's side got off to the worst possible start, tamely allowing Newcastle to race into a two-goal lead through Kenedy (8) and Yoshinori Muto (10), the first time they have conceded two goals inside 10 minutes at Old Trafford in the Premier League.

Nemanja Matic missed a sitter early in the second half, but sub Juan Mata halved the deficit with a fine free-kick (70) to give United hope, and they duly levelled shortly after through Anthony Martial's finish (76) before Sanchez's winner.

The home fans welcomed Mourinho positively before the match, but the mood soon flattened as Newcastle took the lead through Kenedy, curling left-footed into the far post after a simple ball from Ayoze Perez found him one-on-one with the stranded Ashley Young.

It was 2-0 just two minutes later through Muto, turning and smashing past David de Gea from 12 yards for his first Newcastle goal. Man Utd fans replied defiantly, singing: "We love United, we do," while Newcastle fans mocked Mourinho with a rendition of: "You're getting sacked in the morning."

Mourinho reacted, hooking Eric Bailly for Juan Mata after just 19 minutes, and they should have pulled one back through Marcus Rashford, whose close-range header from Romelu Lukaku's cross fell inches wide.

Newcastle could have just as easily been 3-0 up as De Gea saved well from Muto's point-blank header after finding acres behind the back line, before two strong penalty appeals at both ends were waved away by Anthony Taylor for handballs against Young and Muto.

Boos were heard at the break, Marouane Fellaini then replaced Scott McTominay for the second half, but United's back three consisted of Chris Smalling, Nemanja Matic and Pogba early after the restart.

Matic aptly produced a defender's finish after Pogba's deflected shot was saved by Martin Dubravka, blazing over the rebound from six yards when it seemed harder to miss.

Mata made amends, curling home a superb free-kick from 25 yards, before Dubravka came to Newcastle's rescue twice in a minute, beating away Fellaini's half-volley effort and then producing an even better stop from Smalling's close-range strike.

The hosts were level with 14 minutes remaining after a world class move; Martial slipped the ball into Pogba, whose backheel flick gave Martial space to fire past Dubravka and into the bottom left corner from 15 yards.

Mo Diame saw a header cleared off the line by Lukaku at the other end, but the pressure on the Newcastle goal began to intensify. Criticised for his performances since joining the club in January, Sanchez popped up with the dramatic winner, heading home Young's cross from eight yards.
