Thought he started ok but then drifted out the game badly. I don't want to be too harsh since he was playing in an unfamiliar position, but let's be honest he generally does the same thing in the centre.
Also got to say his effort for the first goal we conceded was pathetic, as it usually is when players get in behind him. Just jogs back without any effort. He's ok when the play is in front of him, but once they get in behind he's terrible for just ambling back.
Casemiro was equally to blame for pretty much the same. If either (or preferably both) had actually busted their arse to get back that goal probably isn't conceded, and that goal completely changed the game.
