Manchester United boss Erik ten Hag says Casemiro will improve as he adjusts to the Premier League.
Casemiro started at Everton almost seven weeks to the day since he was paraded at Old Trafford but was dispossessed for Alex Iwobi's fifth-minute goal.
The Brazilian recovered to play a piercing pass for Cristiano Ronaldo to strike the eventual winning goal.
Casemiro, 30, is set to keep his place in the league against Newcastle on Sunday as Scott McTominay is suspended after receiving a fifth yellow card.
"Yeah, difficult, I don't know," Ten Hag began when asked about Casemiro's performance. "The day he came, I repeat myself - I have told this story several times - so I don't know if that's necessary.
"But you see I think he settled in and you see which impact he can have and when he gets games he will be better and better."
