Manchester United defender Tyrell Malacia has praised the positive impact of Casemiro on the squad.
The Brazilian has been a hit with the United fans and players since arriving from Real Madrid in the summer.
Casemiro has played 41 games for the Red Devils in all competitions so far this season.
"Yeah, really, really important," Malacia told club media.
"He's [Casemiro] had a big impact on and off the pitch, especially in the dressing room and on the pitch. So yeah, he's important."
Casemiro was involved for the entirety of United's FA Cup semi final success over Brighton, which they won on penalties.
