Southampton have completed the signing England Under-21 goalkeeper Angus Gunn from Manchester City in a £13.5m deal.
Gunn, who has interested other clubs, has left the Etihad Stadium, where he was behind Ederson and Claudio Bravo in the fight for a first-team place.
He spent last season on loan at Norwich, the former club of his father, retired Scotland goalkeeper Bryan Gunn.
The deal would see an initial payment of £10m for the Norwich-born 22-year-old, with up to £3.5m in add-ons.
Gunn, an ever-present for Norwich in the Championship last season, trained with England before the World Cup, having chosen them ahead of the country of his father's birth.
He joins a Southampton side who shared the goalkeeping duties between Fraser Forster and Alex McCarthy last season.
McCarthy finished the season as first-choice goalkeeper, with Forster's last game the 5-2 Premier League defeat by Tottenham at Wembley on Boxing Day.
Winger Dusan Tadic has joined Ajax for an initial £10m while striker Guido Carrillo has left to join La Liga club Leganes on a season's loan.
It is also thought the Saints have lined up a deal for Denmark centre-half Jannik Vestergaard.
