However, sources say the offer falls far below their valuation and is certain to be rejected.

The 25-year-old, who joined Leeds from Rennes in 2020, has attracted interest from a number of clubs in the Premier League and abroad.

It is felt he would prefer to join Barcelona if the prospect materialised, but it is not known whether the Spanish giants will have the finances to do a deal.

He has scored 17 goals in 60 Premier League appearances for the West Yorkshire club - who would like to keep the player - including the crucial opener from the penalty spot in their final game of last season when they won at Brentford to preserve their top-flight status.

Meanwhile, it is understood Leeds are still to receive an official approach from Manchester City for England midfielder Kalvin Phillips.

Phillips' Elland Road future has been the subject of intense debate since the end of the season.

And while Leeds would like Phillips to sign a new contract to remain with his boyhood club, they are prepared for City to declare their interest and understand it would be tough for the 26-year-old to turn the offer down when it eventually comes.
