They are apparently going to offer him 2+ years bringing him to 2023 with a release clause of €200m. I really don't see him leaving, he's a fan of the club, the fans love him too and he's playing in the current best team in the world this season and thriving.
I didn't think so many people would be saying so too, but I have to agree he's the best in the world for me also this season. He looks completely unstoppable, seems to win every ball. He's a monster physically, has massive talent, and backs it up with great intelligence, has it all. I think he's great to watch too. Some of his defensive touches and interceptions have been majestic, and he has an elegance about him, which isn't normally said about a defender. Check out 2.29 of the video below to see how easily he dispatches Bale and then Benzema, while making it looks effortless. (Tip: mute before watching or your ears might bleed)
Anyway, Ive slathered you with enough praise Umtiti. Fin.
