Mbappe struck his first goals in LaLiga with a brace in Sunday's 2-0 win against Real Betis.
Now back with France, Mbappe said: "I’m very happy to be at Real Madrid.
"Everything is working very well. It’s improving my performance little by little. I’ve scored, so things are working. I come with the same energy as always to the French national team.”
On his return to the Parc des Princes, he also stated: “The stadium is special. I have spent many years here and I have many memories. It’s the stadium I know best from my career at the moment. I have only good memories with my family, with the players. Tomorrow’s reception, I don’t expect much. The most important thing is to win and start the Nations League well.”
