Hi
Nigel thanks for comment. I have looked at that tackle very closely in "super " slow motion. To me it looks like the guy was tackled by two players almost at the same time. One of the tacklers slightly nudged the guy and he dived. The second tackler did tread on his foot after he had gone down. I can see why the decision was difficult,it was almost impossible the detect.

I thought the ref signaled no penalty but changed his mind and went for the VAR.

Regards

Mike
