Liverpool have completed the signing of Newcastle striker Alexander Isak in a British-record deal worth £125m.

The deal eclipses the previous record of £115m which Chelsea paid Brighton for Moises Caicedo in 2023 and brings to an end the longest-running saga of this transfer window.

Newcastle announced Isak’s departure in a pointedly-terse 37-word statement that did not thank him or mention any of his achievements: “Newcastle United can announce the sale of striker Alexander Isak to Liverpool for a significant British record transfer fee. The Sweden international joined the Magpies from Real Sociedad in 2022 and made 109 appearances in all competitions.”

The Sweden international will wear the No 9 shirt and has penned a six-year deal at Anfield, taking Liverpool’s spending to £446m this summer. They have recouped £228m in sales for a net spend of £218m.

“It’s been a long journey to get here,” said Isak. “But I’m super happy to be a part of this team, this club and everything it stands for. It’s something I’m proud of and I’m really looking forward to it.

“I’m just happy it’s done and that I can get back to work. I’m looking forward to seeing my team-mates and the fans, and getting back out there.”

Isak added: “I think I have a lot to give, I think I have a lot to improve. I’m a striker but I always want to give as much as possible to the team, mainly goals but much more than that as well. I want to win everything.”

How Liverpool finally landed Isak

Liverpool had a bid of £110m plus add-ons rejected for Isak at the start of August as Newcastle were unwilling to sell their star man without certain conditions being met.

Although Newcastle stressed they valued Isak at £150m, that stance softened in recent weeks as Isak, determined to explore his options, missed their opening games of the season and said “the relationship can’t continue”.

Isak scored 23 Premier League goals for Newcastle last season and netted their winner in the Carabao Cup final victory over Liverpool at Wembley, which ended the club’s 70-year wait for a major domestic trophy.

Newcastle signed Isak from Real Sociedad in August 2022 for £63m. In total, he scored 62 goals in 109 appearances for the Magpies. To replace Isak, Newcastle have signed Nick Woltemade from Stuttgart and Yoane Wissa from Brentford for a combined fee in the region of £119m.

Downie: ‘Statement sums up how club feel about Isak conduct’

Sky Sports News’ Keith Downie at St James’ Park:

“We’ve spoken about this at length for days, weeks and months and here we are, the deal has finally been concluded.

“Newcastle’s statement is just 37 words, two sentences. It’s incredibly short, usually you’d be thanking players and talking about their time at the club.

“It sums up exactly how the club as a whole feel about Isak’s conduct this summer.

“This is the guy who scored the winning goal in the Carabao Cup final in March to end 70 years without a trophy at the club.

“He was loved by the supporters, there’s still posters behind me down the street, there’s kids walking around with Isak 14 shirts on.

“But this is how he will now be remembered.”
