He was marking Antonio, he has to tuck inside as Tarkowski made a move out to the crosser.
That may be true, but you've seen the replay mate and you know he's slow to get out to block the shot and when he's there, he turns side on so is only half the size he should be.
Turning side on isn't because he's marking Antonio, it's because he doesn't want to take one to the kipper.
He's normally been great at chucking his body on the line but he's deffo started turning his back a bit more the last few weeks. Maybe his new wife said stop taking one to the face otherwise I'm not marrying you, who knows!
