Southampton have completed the signing of goalkeeper Angus Gunn from Manchester City in a deal that could be worth up to £13.5 million.
The England Under-21 international, who has signed a five-year deal, will cost the Saints an initial £10m with a potential further £3.5m in add-ons. City also have a buyback option.
Southampton manager Mark Hughes said: "Angus is a player who clearly possesses a tremendous amount of potential, but his performances for Norwich and for the England Under-21 team also demonstrate the capabilities he already has right now.
"We believe he has all the credentials to become a full international goalkeeper for England in the future, and that's exactly the sort of talent we want to have here at Southampton.
"He represents another excellent addition and we are excited about what he brings to the squad and the further progression we feel he can make with us.
"There was a lot of interest from other teams in the Premier League, so for Angus to choose Southampton as the best option for him is another positive indication of the work the club is doing and what is being built here."
Gunn, 22, spent last season on loan at Championship side Norwich City and earned a call-up from England boss Gareth Southgate for an international training squad.
At City, he would have been behind Brazil international Ederson and Chile goalkeeper Claudio Bravo in the battle for the No. 1 jersey.
Said Gunn of the move: "The opportunity was there for me to stay at Manchester City but I saw the potential of this club and the squad. The manager and Dave Watson were a big part of the reason why I have chosen to join and speaking to them both was a big factor in my decision.
"I think the club has got a big future and I'm looking forward to getting started now."
Southampton finished last season with Alex McCarthy as their goalkeeper after first-choice Fraser Forster lost form.
