Stoke have announced the signing of Tom Ince from Huddersfield for an initial £10million.
The fee for the 26-year-old winger, who has agreed a four-year contract with the Sky Bet Championship side, could rise to £12million with add-ons.
Potters boss Gary Rowett, who previously managed Ince at Derby, told his club's website: "I've had the fortune to work with Tom before and he's a terrifically talented player.
"He's very strong technically and can play anywhere across the front three, but he's particularly good from the right-hand side."
Ince joined Huddersfield from Derby on a three-year contract last summer.
He scored twice in 33 Premier League appearances as David Wagner's Terriers avoided relegation.
Town boss Wagner told his club's website: "The value of this deal made sense for us. Tom is a good player, but I'm comfortable that we have good options in the wide positions.
"We would like to thank Tom for all his efforts and hard work in the last season and wish him the very best for the future."
