Nicolas N'Koulou hasn't been unsettled by talk of a move away from Marseille.
He said: "When you are a player and you are being connected with all the big clubs in the world it is flattering, but you should not lose your head. You need to work harder and have the appetite to improve yourself.
"I love Marseille and am happy to play for the biggest club in this country.
"The challenge we face today with the big spenders like PSG is fascinating.
"I am staying to test myself against the Ibrahimovics of this world."
