The Brazilian sealed a 2-1 win away to Athletic Bilbao on Saturday and his countryman was quick to praise his development after a battling victory
Real Madrid full-back Marcelo hailed Casemiro as one of the best midfielders in the world following his match-winning display against Athletic Bilbao.
The Brazilian struck a second-half winner to seal maximum points after Aritz Aduriz had cancelled out Karim Benzema's opening goal at San Mames.
The goal capped a hugely impressive all-round performance from the 25-year-old and his compatriot believes he has come on leaps and bounds in recent seasons.
"Casemiro has improved amazingly," he told BeIN Sports.
