Legendary pundit Eamon Dunphy feels Casemiro is Manchester United's best signing in a decade.
And Dunphy thinks the Brazilian is the main reason behind United's improvement this season.
"In last year's Champions League final, he stood up for Real Madrid when it mattered most. He was 30 years old and had already won the Champions League four times. But he fought for every blade of grass on that pitch to make sure that he got the fifth medal,'' he said in his Irish Daily Star column.
