Nikola Vlasic has left Everton for CSKA Moscow for a deal believed to be worth around £14m.
The Croatia international played 19 times for Everton, having signed from Hajduk Split for £10m in August 2017.
The 21-year-old struggled to hold down a regular first-team place under former bosses Ronald Koeman and Sam Allardyce before being shipped out on loan by Marco Silva.
Vlasic scored eight goals and registered seven assists in a successful loan spell with the Russian giants last season.
