Leicester City manager Claude Puel has declared that he is "delighted" by the arrival of James Maddison at the King Power Stadium.
The 21-year-old, who has signed a five-year contract with the Foxes, joined the club from Norwich City for an undisclosed fee.
"James is a wonderful player who is one of the most exciting young talents in English football," Puel told Leicester's official website. "He made a big contribution to Norwich City last season and I'm delighted that he has decided to make the step up to the Premier League with Leicester City Football Club.
"He's a young player who can create things in the attacking third and will give us even more possibilities in the squad. Of course, he has good ability and also good potential to develop even more, which is exciting for the team and for the supporters."
Maddison scored 14 goals and provided eight assists in 44 Championship appearances for Norwich last season.
