According to Torino Granata [1 December], Roma are also interested in signing the 26-year-old during the January transfer window.
So yet, no bids have been made for the Serbia international, but negotiations are expected to begin when the World Cup concludes in late December.
Leeds needed midfielders over the summer, and the scouting staff deserves credit for resolving the issue quickly and effectively.
Tyler Adams has been an exceptional acquisition and while Marc Roca has been decent as well, his impact has certainly been felt.
Brenden Aaronson, who plays in a more advanced role, does tend to drop deep on occasion as well and that could be seen as three midfielders being signed over the summer.
Leeds need a left-back and a striker in January, and even if they wanted Lukic, it would have been difficult to compete with Manchester United.
The Red Devils have vast pockets and could easily overpay for the 26-year-old if they wanted to sign him before the Whites.
Jesse Marsch, too, is unlikely to prioritize a move for another midfielder, and he has previously stated his desire for a new striker in January.
