He said: "I could have left. I really thought about joining PSG. Returning to France, playing in Paris, it was a real possibility among others.
"But I don't want to talk about it due to my respect for Chelsea.
"There will not be any problems with Chelsea for a long time. Everything will go off smoothly this season.
"We have a big squad at Chelsea which will allow me to have some rest and give me energy for the French team, which is important to me."
