Alexander Isak helps Liverpool move closer to securing Champions League action

Andy Robertson was also on target in the 3-1 defeat of Crystal Palace.

British-record signing Alexander Isak scored as Liverpool moved closer to securing Champions League football next season but the 3-1 victory over Crystal Palace owed as much to third-choice goalkeeper Freddie Woodman .

Isak, in only his fifth game back since fracturing a fibula at Tottenham in December, has naturally taken time to rediscover his sharpness after four months out.

But his opening strike was an example of why the club spent £125million to sign him in from Newcastle last summer, displaying the sort of instinctive finishing which the team has lacked.

Florian Wirtz scoring in added time, his first since January, secured a third successive league win and moved Liverpool up to fourth, eight points clear of sixth-placed Brighton.

Palace’s 71st-minute goal, controversially scored by Daniel Munoz – who lobbed the ball into an empty net with Woodman laid injured – had subdued the mood.

The other only cloud on a sunny afternoon was the sight of Mohamed Salah going off with an apparent hamstring injury.

With only four matches remaining fans may well have seen the last of the club great on the pitch before his departure this summer after nine years but he contributed plenty to a third successive league win.

Palace’s focus is on Thursday’s UEFA Conference League semi-final against Shakhtar Donetsk but they took the game to their opponents, outnumbering and outmanoeuvring them in midfield.

Chris Richards headed over and Brennan Johnson wasted another chance before Liverpool thought they had won a penalty when Salah was brought down by Johnson – but VAR spotted the Palace player had got a touch on the ball.

The breakthrough came in the 35th minute when Alexis Mac Allister’s scuffed shot was controlled by the Sweden international, allowing the ball to drop before bouncing a left-footed shot beyond Henderson.

On the counter-attack Jones slid in Robertson to guide a shot inside the far post.

Most of his team-mates celebrated with the departing left-back but central defenders Virgil van Dijk and Ibrahima Konate rushed to congratulate Woodman, a Palace academy graduate.

The Kop sang his name and the soon-to-return Alisson Becker applauded from the bench, with “England’s number one” ringing out after he clawed Maxence Lacroix’s header off the line.

Half-time Palace substitute Borna Sosa dragged a shot wide, Jaydee Canvot nicked the ball off Isak as he was about to pull the trigger, Salah was forced off and then came the visitors’ disputed goal.

Woodman injured himself saving from Ismaila Sarr and Munoz saw his opportunity to reduce the deficit.
