Griezmann continues to be linked with a €100m move to Barcelona at the end of this season.
Luis stated: "Griezmann is a step above the others at the technical level. Few have gone through here with his quality.
"I left Atlético and I had the opportunity to come back and I am very happy. There are players who want to change and I hope that this is not his case.
"He can write an eternal story at Atlético Madrid. He is very happy, very happy, he has a team playing for him."
