Looked it from the WSU as well.
Certainly wasn't a free-kick to them shortly afterwards. Thought he got a lot wrong last night.
My instinct at the time was that it was (1) just outside the penalty area and (2) not a foul, as defenders are not obliged to move out of your way.
He was awful. The advantage rule particularly bugged me, very consistently applied, twice we were away and he pulled play back.
His overall interpretation at times was bizarre.
Very poor.
