Don't know. Lenglet is coming of a poor season but still think in a different (more defensive) system he could do very well. Think he'd do well in Serie A but problem is Italian teams don't have much money. And as said before I think he could even recuperate some of his form here if paired with a better leader and more athletic CB.
And clearly any team potentially interested in Griezmann would consider him not performing up to his expected level here due to him being a misfit. He's shown his class over his career and still has 3-4 good years ahead of him imo.
I see Lenglet as a Pique-type, with his heads in the clouds, but also with a massive advantage over him which is basically age. Pique has no incentive of recovering, he's had his days and now is just a buffoon. Lenglet could still have motivation left. Umtiti is another case, he is purely finished from an athletic point of view. And between Lenglet and Pique, due to the horror of seeing Koeman start both in the first 11, Pique should be sacrificed. For the good of the team. Also, Pique is no leader. He's just masquerading as one in social media and talk shows.
As it stands, I'd play Lenglet and Araujo. With Mingueza pretty close to Araujo. Garcia is an unknown factor for me.
