I don't think he really did anything except hit a header straight at the keeper when anything to his left would have gone in. Two corners were good and two were utterly terrible.
He was no further upfield than Lyanco and Salisu found themselves at times, and he made some great interceptions.
I'd Ralph is making a switch to back 3 then I can see it working.
Lyanco does seem to overcommit to headers when the ball comes forward in the air, takes himself out the game when he has no chance of getting to the ball.
