Chelsea are among a number of Premier League clubs looking at Croatian midfielder Josip Vukovic as they plan their possible summer business.
The Blues have been hit with a transfer embargo lasting two windows but should be able to make moves in the summer if they appeal the punishment from FIFA.
Christian Pulisic is already scheduled to join the club in July after they concluded a deal for the player last month with Borussia Dortmund.
And as they attempt to ready themselves for their ban, Maritimo ace Vukovic is player they taken a look at.
Benfica and Rangers continue to watch the player with his impressive form in 2019 seeing increased interest in his services.
A defensive midfielder, he’s also been scouted by Leicester City, Watford, and Wolverhampton Wanderers, with a fee of around £4million thought to be enough to prise him away from the Portuguese side.
The 26-year-old joined the Primeira Liga side in 2018 from Olimpik Donetsk and has impressed, most recently in the club’s 0-0 draw with Sporting Lisbon.
Vukovic has made 16 appearances this season for the team currently managed by former Portugal international Petit.
Once a Croatian Under-19 international, he revealed to Portuguese outlet Record he still dreams of a senior call-up for his nation.
