First half he was poor, got square on attackers, something he does all the time and obviously slow to react for their goal. Fantastic delivery for Fernandes' goal and better 2nd half against a really poor Betis.
Probably unlikely to get a rest though as we'll want to win the game early and then hopefully give Malacia minutes so he can find some rhythm to go into the Betis game, where he may start.
It's not a recent thing. He's always been lacksadical with his boxing out and closing down the space. It's why he works as a centre back so well at times as he has a natural tendency to drift inwards towards the penalty box and doesn't like facing attackers down the channels/in open space. He's very capable of doing and shutting players down, it's just not a consistent thing of his.
