Newcastle have signed Tino Livramento from Southampton for an initial £32m.
The Magpies have tied down Livramento, who came through Chelsea's academy, until 2028.
The 20-year-old full-back was in the stands at St James' Park as Newcastle rounded off their pre-season preparations with a comfortable win against Villarreal on Sunday.
Livramento becomes Eddie Howe's third summer signing, following Sandro Tonali and Harvey Barnes.
Southampton signed Livramento from Chelsea in the summer of 2021 for £5m.
An ACL injury suffered in April 2022 prematurely ended what had been an impressive breakout season and consigned the England U21 international to more than a year out on the sidelines.
Livramento returned to action 392 days later against Brighton at the Amex - the same venue he picked up the injury - off the bench as one of two substitute appearances he made last season.
