He was great in his first season, because Pjanic was great too. Left him to do his job without needing him to play with the ball. After Pjanic fell off, so did Matuidi, because he was expected to do more and clearly couldn't.
True. Some of us need to have true abilities for parasites like you and Matuidi to suck us dry. When I communicate with someone like you I completely understand Ronaldo's frustration when he interacts with Matuidi and Danilo.
