Chelsea are at the front of the queue for Eintracht Frankfurt striker Luka Jovic, according to a report.
The 21-year-old has struck 23 times in 37 appearances for the Bundesliga side this season, where he is on a two-year loan from Benfica.
Frankfurt are certain to trigger the option to buy Jovic outright in the summer, but they face a battle keeping him at the club for another season.
Manchester United have shown a rumoured interest in the Serbia international, as have Arsenal, Barcelona and Real Madrid, though AS claims that Chelsea are the frontrunners to sign him.
However, Frankfurt are holding out for a monster fee for Jovic, with a bid in the region of £67m likely being required to prise him away.
