A persistent thigh problem requires Denis Cheryshev to undergo surgery, placing him in doubt for Russia's Euro 2016 campaign.
Denis Cheryshev's hopes of representing Russia at Euro 2016 have suffered a blow with the midfielder set to undergo surgery on his thigh.
Cheryshev joined Valencia on loan from Real Madrid in February but has made just seven appearances in all competitions, having suffered a thigh injury against Atletico Madrid in March.
The midfielder made his return after almost two months out in the 2-0 defeat to Villarreal on Sunday but suffered a recurrence of the problem.
