Stoke City have signed Watford and England under-21 centre-back Ben Wilmot for an undisclosed fee.
He played a pivotal role in Watford's automatic promotion-winning campaign in the Championship last season, making 25 appearances for the Hornets.
"I've no doubts he will be an excellent addition to our squad," Stoke manager Michael O'Neill said.
"Ben is a young player of enormous potential, who already has great experience of Championship football.
"I know he was attracting interest from a number of other clubs and we're really pleased to have made him our first signing of the summer.
