Adam Idah has signed a permanent deal to join Celtic in the Scottish Premiership for an undisclosed fee.
Idah leaves having scored 17 goals in 116 senior appearances for the Canaries.
The Irish international is a product of the Norwich City Academy, previously competing for the club's Under-21 and Under-18 sides since joining in 2017 from College Corinthians in Ireland.
Before spending time on loan with Celtic in the second half of last season, Idah provided City fans with some dramatic moments to celebrate including late winners against Hull City, Cardiff City and Bristol City in the Sky Bet Championship.
Sporting director Ben Knapper said: "Adam leaves with our very best wishes. He has a great opportunity at Celtic to continue his progression.
"The academy staff have taken great pride in seeing Adam develop from a youth team player into the senior squad, and going on to become a full international with the Republic of Ireland. So many people here played a part in his journey, and he and everyone should be really proud of that.
"Everyone at Norwich City wishes Adam the very best for the future."
