Manchester United boss Erik ten Hag believes Casemiro's attitude is part of the reason his team is on such an upward trajectory.
The Red Devils have made remarkable progress since their start to the season, when they lost their first two Premier League games.
Aside from improving the players technically and tactically, ten Hag believes the mentality of winners such as Casemiro is adding a lot to the dressing room.
Yeah, of course," he replied when asked by United's in-house media if Casemiro is world-class.
"I think we are so proud of him [being on FIFA Best Team of the Year].
"I think he showed how important he is and how he contributes to our team - in the dressing room, not only on the pitch.
He is important, everyone can see that, but also around to construct the climate which is necessary to win trophies, and he is showing by example the squad all the example on Sunday. And it's great to work with him.
"We are so happy with that, it's a big reward, I'm so happy for him to be rewarded to be in the World Team of the Year. That is really a reward and so wonderful."
