Bournemouth have completed the signing of winger Dango Ouattara for around £20m from French side Lorient.
The 20-year-old has scored six goals and provided six assists in 18 Ligue 1 appearances this season.
Ouattara, who has five goals from 11 international caps for Burkina Faso, joins on a five-and-a-half-year deal.
Bournemouth's new American owner Bill Foley recently bought a minority stake in Lorient. He had also been interesting West Ham.
Foley has pledged to strengthen boss Gary O'Neil's squad in an attempt to guide them away from the Premier League relegation zone.
"We are pleased to secure the services of Dango, a promising and sought-after player with a great deal of potential," Cherries chief executive Neill Blake said.
"We have been monitoring him for a period of time and he fits the profile of the young, ambitious, hungry and hard-working player this club is looking to recruit."
