The Portugal international picked up the Premier League Player of the Month award in February, his first full month at Old Trafford.
And Matic has been mightily impressed by his new teammate.
"Because I follow the Portuguese league, I knew he was good – even though he played for Sporting! But I'm very surprised he adapted so quickly to the Premier League," Matic, who played at Benfica, said.
"He brings us a lot of qualities, like the confidence he has on the pitch, he always knows what he wants to do with the ball."
