Southampton have signed former Norwich number one Angus Gunn in the belief he will become a fully fledged England international.

The 22-year-old was an ever-present in the Championship for the Canaries during a season-long loan from Manchester City last season, earning a senior call-up for a friendly against Brazil and training with Gareth Southgate's squad ahead of the World Cup.

Norwich-born Gunn, the son of Canaries legend Bryan, was voted into third place by fans in the player-of-the-season stakes and has become the established first choice for the England U21s.

That persuaded Saints boss Mark Hughes to bring in the former Norwich keeper, in a deal reportedly worth £10m up front and potentially rising to £13.5m, signing a five-year contract. He is expected to compete with Alex McCarthy for the gloves, with Fraser Forster set to leave.

'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,' Hughes said.

'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.'

Hughes and former Norwich goalkeeping coach Dave Watson, now at Saints, persuaded Gunn to choose them amid interest from other Premier League clubs.

'The opportunity was there for me to stay at Manchester City but I saw the potential of this club and the squad,' Gunn added, speaking to Saints' website.

'The manager and Dave 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. I've spoken to Dave Watson and he said it would be a great environment to come in to work. It feels really good and I'm buzzing to get going.'
