Juergen Klopp tasted victory at Old Trafford for the first time as Liverpool breathed new life into their top-four push with a thrilling 4-2 win in the rearranged fixture against Manchester United.

After anti-Glazer protesters got into the ground and onto the pitch 11 days ago, further demonstrations could not stop Thursday's Premier League fixture going ahead in Old Trafford's final match behind closed doors.

United missed this chance to all but end Liverpool's Champions League qualification hopes as their fourth match in eight days ended in a first home loss to their bitter rivals since 2014.

Stand-in skipper Bruno Fernandes' deflected effort had got Ole Gunnar Solskjaer's side off to a dream start, only for Diogo Jota to level with a smart flick after a penalty decision was overturned.

The equaliser came from a corner and United's soft underbelly from set-pieces was again exposed in first-half stoppage time, with Roberto Firmino heading home Trent Alexander-Arnold's excellent free-kick.

Liverpool pulled further ahead 72 seconds after half-time as a comedy of errors at the back ended with Firmino turning home his second of the evening.

United looked punch-drunk but eventually rallied as Marcus Rashford reduced the deficit before Nat Phillips, who had deflected home Fernandes' opener, cleared a Mason Greenwood attempt off the line.

Mohamed Salah ensured United would lose their sixth home league game of the season, racing through at the death as Liverpool moved into fifth and four points behind Chelsea with a game in hand.

Klopp was delighted to bag all three points.

"Great fight, good game, intense - how a derby should be and our first, since I am in Liverpool, win at Old Trafford," he told Sky Sports. "Good timing I would say. We needed it, obviously, and we fought hard for it and deserved it, so all good.

"It was necessary. Without this result, we don't have to talk too much about it. We are still in the game and in the race. That is all we could do tonight and we did that."

Earlier, Everton's European hopes suffered a blow with a damaging goalless draw at Aston Villa.

The Toffees failed to find the win at Villa Park on Thursday which would have kept the pressure on the Premier League's top six.

They climbed to eighth, above Arsenal, to move two points behind fifth-placed West Ham.

Boss Carlo Ancelotti warned afterwards Everton would need to win their final three games of the Premier League season to qualify.
