Over the last two summers, since Neymar's departure for PSG, William's name has been heavily linked at the Camp Nou.
The skilful Brazilian striker still is, as he always has been, on their agenda.
Barça have not taken their eye off him and, as the media suggests, 2019 could be the year that the Chelsea player lands in Barcelona.
'The Sun' dared to say that, with complete certainty, Barcelona will go all out with an offer of 35 million euros.
A more than tempting proposal considering that Willian's contract ends in 2020. He also turns 31 in August.
However, Chelsea's transfer sanction, issued by FIFA, could complicate or make the operation more expensive.
In recent years, William has been one of Chelsea's most prominent players alongside Eden Hazard.
In all, the Brazilian has a total of 289 appearances with Chelsea since joining the club in the 2013-14 campaign, having scored a total of 52 goals.
