Ruben Amorim believes that the current statistics of Casemiro are proof that he finally gets the best from the Brazilian star in Manchester United.
The future of Casemiro in Old Trafford was in question before Amorim succeeded Erik ten Hag in November, whereby the club wants to move its £ 375,000 a week's salary of the wage account.
The five-time Champions League winner fell under the young Toby Collyer in the pecking order of midfielders, where Amorim demands that his players like Mad Dogs 'Run'.
But after another insured representation of Casemiro in the beautiful 3-0 Europa League semi-final victory over Athletic Bilbao on the San Mames on Thursday evening, Amorim claims that United has found a way to get the best out of the 33-year-old.
“I think he has improved a lot,” said the United Boss. 'You can't see how he plays, but the way he runs. You can see it. We have the data to show him where he worked very hard. He is a very good example.
'Even Toby sometimes played for him, and now it is difficult to take Casemiro (from the team). So it's a lesson for all players in Manchester United. Whatever the past or the last month is, everything can change at one time. '
Amorim accepts that Casemiro is not able to do the high press he wants and would like to leave the experienced midfielder deeper to help at the back, while wingbacks such as Noussair Mazraoui, Patrick Dorgu and Diogo Dalot participate in the attack.
He added: 'We understood that he cannot jump with high presses all the time. Sometimes it is better to place three defenders and let him be the fourth defender and let the wingbacks press high. These are all things that we understand and try to tackle all the team's criticism. But the credit is for Casemiro. '
