CSKA Moscow have signed midfielder Nikola Vlasic from Everton in deal worth about £14m.
The 21-year-old, who has signed a five-year contract, scored eight goals in 31 matches for the Russian Premier League club while on loan last season.
CSKA announced on Wednesday that Vlasic had signed his contract, and Everton confirmed the move on their website.
The Croatia international played 19 times for Everton, having signed from Hajduk Split for £10m in August 2017.
However, he made only six appearances after Sam Allardyce replaced Ronald Koeman as manager the following November, before Marco Silva took over and sent the midfielder out on loan last August.
In January, the midfielder said he had no future at Everton, adding: "I expect them to sell me as soon as they get their first bid."
At CSKA, Vlasic scored against Real Madrid in a shock Champions League victory last October.
