Willian revealed why he rejected an offer from Barcelona to stay at Chelsea.
The winger has been subject of transfer speculation over the last 18 months but a move has so far not materialised.
Willian explained exactly what happened when he had the chance to move to Barcelona.
“The only real official offer I had came from Barcelona, last year, after the World Cup,” Willian told DAZN series Saudade.
“Barcelona indeed presented an offer to Chelsea but it was rejected.
“That was the only actual time I had to discuss something like this with my family, although we really love it here [in London]. So there were several factors that helped us in staying.”
The 31-year-old joined Chelsea in 2013 from Russian side Anzhi and has gone on to play more than 300 times.
His current deal expires in the summer and he is thought to be keen on staying at Stamford Bridge.
Willian did also reveal he would one day like to return to his boyhood club in Brazil.

He continued: “If I have to return to Brazil, I’d like to play at Corinthians again.
“It represents a lot, I was born and raised there, my footballing career began there when I was nine, I’ve spent my entire childhood there.
“I’ve been a Corinthians fan since I was little, even before I played there, my family also supports the club. ‘So when I got there all my relatives were very happy, and then, after I got to the first team, everyone was overjoyed.”
