Barcelona scouts will watch CSKA Moscow midfielder Aleksandr Golovin play in Russia's round of 16 match against Spain on Monday morning AEST, according to reports in Spain.
Golovin, who has been capped 21 times for Russia since his senior debut in 2015, starred for the host nation in their opening two matches.
He was rested for the defeat to Uruguay in their final group game.
"Two Barca scouts, Goran Vucevic and Bojan Krkic are there, following the tournament in Russia. They know him well, but a game like that - a life-and-death game - will help to evaluate him," reported Spanish daily Mundo Deportivo.
The newspaper added that Golovin was considered to be a player of the same standard as Tottenham Hotspur and Denmark midfielder Christian Eriksen, but "much more affordable in terms of transfer and salary."
Earlier, Italian side Juventus were also reported to be interested in signing the 22-year-old Russia midfielder, but are thought to have failed to reach an agreement with CSKA.
Golovin’s current contract lasts until the end of the 2020/21 season. He has made 113 appearances and scored 13 goals for the club.
