I just watched the replay. Oddly it was Lowton who let Lugano go for the free header. Why Lowts was on that side I have no idea.
My bad, I thought for sure I saw number four
nearest to Lugano.
Well your eyes did not deceive you. Its weird. He does peel away at the very start of the free kick, leaving Lowts to cover Lugano. Lowts who should have been covering where Ron went doesnt pick up Rons man.
Very odd.
Hmmm, I figured it'd have been Vlaars responsibility because you'd want a CB marking their cb, but you're right it is an odd play. Maybe he yelled at lowton to pick up Lugano and lowton didn't hear him?
Could be, it was just weird. Anyway as you rightfully say, not his finest hour, or lowts.
