Willian says he intends to stay at Chelsea and confirmed Barcelona made a bid to sign him.
The Brazil winger, 29, has been at Stamford Bridge for five years but was linked with a move away this summer.
“The only club I knew that really made an official offer for me was Barcelona.”
He has also been linked to Manchester United and Real Madrid – who are also reportedly interested in Blues duo Thibaut Courtois and Eden Hazard.
Willian added: “I have my head here and I intend to continue in the club unless the club wants to sell me.”
New Chelsea manager Maurizio Sarri has only signed two players this summer – Napoli midfielder Jorginho and back-up goalkeeper Rob Green. BBC .
