RC Lens have set an asking price of €25m for Montenegro midfielder Andrija Bulatovic, with Borussia Dortmund and RB Leipzig reportedly tracking the 19-year-old.
According to Sky Sports Germany, both Bundesliga clubs are monitoring Bulatovic as they assess the possibility of making a move for the highly rated player.
Bulatovic established himself in the Lens first team last season and has made seven appearances in all competitions during the current campaign.
His progress has also attracted attention from Saudi Arabian clubs, who expressed interest during the summer transfer window. However, the midfielder stayed with the French Ligue 1 side.
Despite his age, Bulatovic has already won 12 senior caps for Montenegro, underlining his growing importance at international level.
Lens recently extended his contract, keeping him at the club until June 2030.
That long-term agreement has not ended speculation over his future, with Borussia Dortmund and RB Leipzig reported to be considering approaches for the midfielder.
