After Barca's second bid of €59m was rejected, they returned with an offer of €61m. But this has also been turned down within hours, and it is threatening to become the new transfer saga of the summer.
Sport claims that Manchester United are also interested in signing Willian, but Maurizio Sarri wants to keep him at Stamford Bridge and it seems that this story may have some way to go yet.
Barcelona felt that Chelsea were in a vulnerable state where they could be stripped of their best assets, due to missing out on a place in the 2018/19 Champions League.
Barça's rivals Real Madrid are hoping to take advantage of this situation as well, as they have been heavily linked with a double move for the Belgian pair of Eden Hazard and Thibaut Courtois.
Chelsea, despite their damaged status, are in no mood to sell on the cheap, but they will consider selling Willian at the right price. He will turn 30 on the eve of the new season, so he may be entering the twilight years of his career.
Mundo Deportivo reports that Barcelona have offered Ousmane Dembele to Chelsea as a makeweight, but the Blaugrana vociferously deny these claims.
They claim that Dembele will not leave the Nou Camp under any circumstances, and his place in the squad will be unaffected even if Willian arrives as a rival on the right wing.
