Spartak Moscow will pay Chelsea £4m to sign Victor Moses on a permanent deal should they qualify for the UEFA Champions League this season.
Moses, 30, linked up with the Russian Premier League club on loan last summer.
The winger has scored three goals and provided two assists in 17 league appearances for Domenico Tedesco’s side.
Spartak Moscow occupy third position on the Russian Premier League table with 53 points from 28 matches.
A win against Khimki on Monday (today) could boost their chances of grabbing the final Champions League spot before the final game of the season on Sunday.
