Willian insists he will not be leaving Chelsea during the January transfer window, despite his lack of first-team action this season, reports the London Evening Standard.
The 29-year-old midfielder has been linked with a move to Manchester United, Barcelona and Brazilian club Palmeiras in the last few months.
When asked if he is staying at Stamford Bridge, Willian said: "I am always happy at Chelsea. I really like this club a lot with my heart.
"The fans can be calm [about him leaving]. I am a Chelsea player and I am very pleased with the way I have been playing in recent weeks.
"When I play I always try to do my best. I try to help the team to play well, to score goals and make assists. Against Huddersfield I did that with my team-mates."
