Casemiro says playing for Manchester United has met expectations.
The Brazil midfielder left Real Madrid for United a year ago.
He said: “It's exactly what I thought.
"The main thing is that there is no easy game here, the first one plays against the last one and is not sure of winning. If you do it with only 90% of your strength, you lose.
"I like the Premier, they are the games with the best atmosphere.
"Everything is great, I was told that Manchester was a difficult city to live in, but I love it.
