The main analysis of the Rashford incident seems a little odd. He starts by saying that the goal could have been ruled out but then (correctly) identifies that there was no break of any of the offside rules.
The more I look at this the more it appears to have been an excellent decision by the referee team. Had they gone the other way, it would have been wrong and var should have told them to look at it again as it would have been a clear and obvious error.
That said, I can see some sense in amending the rules to reflect the fact that a goalkeeper might be put off as a result. Will be interesting to see what they do.
