The Portuguese coach has arrived in Manchester as he gets to work at Old Trafford and the midfielder hopes that the new coach can replicate the success he enjoyed at Sporting Lisbon.
Casemiro said: "We have not spoken, but everyone speaks so well of him. Above all he is very true, very loyal. We cannot ignore how he has changed Sporting. We know that Sporting won many titles, changed the club with titles, with trophies.
"He has already proved that he is a coach that has won a lot. I think there is going to be a good template that everyone wants to grow, everyone wants to learn. I think that is the way to first help us grow to be at the top of the table."
The Brazilian thinks he had a good season at United so far despite coming in for heavy criticism following a poor performance in the 3-0 home defeat to rivals Liverpool in September.
Casemiro said: "I only had the Liverpool game, right?
"The whole team was not good in that game, or this season. This match, but individually, of course when the goals are missed, of course it ends up hurting the team more, but I think it's been a good season for me."
The midfielder thinks that he is building a strong partnership with Manuel Ugarte following the Uruguayan's summer arrival from PSG.
He said: "I have a good connection with him. When one goes forward, the other covers, and vice versa. That is how it has to be, one compliments the other.
"He is a great person. He's a good kind of person. Then, little by little he is also showing that he is a national team player from Uruguay, from a team that has good players. Then he has total respect, not only mine, but all the players."
