I don’t know either, I watched on Sky, it’s possible they played something back or showed a replay that I missed, but all I’ve seen for sure is that Rudiger reported it to the ref.
Bearing in mind Tyler and Neville didn’t talk about anything else for the rest of the game and that the club made multiple announcements about unacceptable behaviour it must have been pretty bad.
I’d like to see it get taken seriously for a change, if it was a spurs fan then we should be given a huge point fine, take 10/15 points off of us, it’s only such a response that will fix this.
