Manchester United suffered a humiliating 3-0 loss to Liverpool at Old Trafford last Sunday.
Most of the United players produced an underwhelming performance, but Casemiro received the most criticism.
The Brazilian was at fault for the Reds’ opening two goals and his overall display was abysmal.
He also lost possession on 14 occasions and won just two of his five ground duels.
However, former United star Nicky Butt isn’t happy with the recent criticism of Casemiro which he thinks is unfair.
