Alexander Isak has completed a record-breaking transfer to Liverpool, with the English Premier League club paying Newcastle United a British-record £125 million ($170 million) for the Swedish striker.

The 25-year-old’s move, which concludes one of the summer transfer window’s most protracted sagas, marks the latest significant outlay in a season of soaring Premier League spending. The fee surpasses Liverpool’s previous British record acquisition of Florian Wirtz and Chelsea’s purchase of Moises Caicedo.

Liverpool’s acquisition of Isak is a key component of a summer spending spree that has exceeded £400 million, following the club’s record-tying 20th English top-flight title. Meanwhile, the sale provides a substantial financial injection for Newcastle, which responded by signing two new strikers.
