Arsenal are one of a number of top clubs monitoring young Russian striker Fedor Chalov, Sky Sports News understands.
Monaco and Sevilla are also keen on the 21-year old, who was top scorer in the Russian Premier League last season for CSKA Moscow, scoring 15 times in 30 appearances.
Chalov scored against Arsenal in their Europa League quarter-final second leg meeting in 2017/18.
In this season's Champions League group stage, Chalov was a goalscorer in CSKA's shock 3-0 win over Real Madrid at the Bernabeu.
Before turning 21 in April, he was called up to the national team, making his debut against Belgium in March in a Euro 2020 qualifier.
He has three years left on his contract at CSKA.
