In the interview, Mbappe said: "We often talk with Antoine. I love his son, he's a football fanatic, he reminds me a bit of myself when I was little. I love him, Amaro. But after that, it's true that it's complicated because we're in a city where our two teams are real rivals.
"But I can assure you, we have a very good relationship with Antoine. He's already invited me to his house quite a few times for a barbecue. It hasn't happened yet, but we're sure to get there. We live next door, in the same building."
The Madrid forward further claimed that he was aware of Griezmann's retirement decision before he made the formal announcement. He added: "Not only did I know he was going to quit, but he also explained why. But it's always the same, it's his decision, only he can explain to you why he made that choice."
