The France international admitted that Paris Saint-Germain made contact with him during the summer transfer window.
“There was no urge to go elsewhere after the World Cup,” he said in an interview with RMC Sport.
“There were other clubs interests but after talking to Chelsea, things were clear. The club is counting on me and I feel good. The next logical step was to continue to Chelsea.
“There were some contacts [from PSG]. But after a discussion with Chelsea I realised that the main thing was to feel good where I was. I am at Chelsea. It's good for me to stay at Chelsea.”
Chelsea will play against Cardiff City at Stamford Bridge on Saturday as Maurizio Sarri's side look to make it five wins from their opening five games of the campaign.
