Bournemouth have completed the signing of France Under-20 striker Lys Mousset from Le Havre on a four-year deal.
The 20-year-old becomes manager Eddie Howe's third signing of the summer following the arrivals of Chelsea defender Nathan Ake on a season-long loan and midfielder Emerson Hyndman on a free transfer from Fulham.
Sky sources understand Bournemouth paid Le Havre £5.4m for Mousset, who impressed last season in French Ligue 2, scoring 14 goals in 29 matches.
"Lys is another player with great potential that we are delighted to bring to the football club," Bournemouth chief executive Neill Blake told the club's official website.
"We're always planning for the future and Lys is not only a young player with exciting potential, but someone who had a massive impact for their club last season.
