The 27-year-old has admitted he is unsure if he will remain with the French capital club beyond the end of this transfer window.
"Football is a sport where confidence is everything," he said.
"When a club wants you, calls you, they want to make you part of their project, they are looking for you.
"A change of club does not solely depend on the wants of the player, there have to be different movements among clubs.
"I have a four year contract with Paris. The Premier League or the Bundesliga? I like them a lot but I am not used to constantly changing league.
"Germany, Spain, Italy and England have the best leagues. But France are progressing."
