Willian revealed Barcelona has made an official bid to sign him from Chelsea.

Willian has also been a long-term target for Jose Mourinho at Manchester United.

"I'm a Chelsea player," Willian told ESPN after Sunday's Community Shield loss to Manchester City at Wembley. "I always made it clear that what I wanted was to stay in the club.

"The only club I knew that really made an official offer for me was Barcelona. But I have my head here and I intend to continue in the club unless the club wants to sell me. But my head is here in the club."
