Newcastle United have turned defender Lewis Hall's loan move from Chelsea into a permanent switch for £28m.
The 19-year-old joined the Magpies last August and made 22 appearances, scoring twice, during the 2023-24 season.
"I am extremely proud to be able to build on last season and continue my journey at Newcastle United," said the England Under-21 left-back.
"When you pull on the black and white shirt, there is no feeling like it and playing in front of the best supporters in the country is extra special for me, being a Toon fan.
