Having watched the game via iFollow and having the benefit of replays, I feel confident to say that there was a very strong argument for a red card (tackle on Rodriguez) and more than a few yellows that weren't given. Again, it was evident that the assistants did not assist. If they see a foul and have an opinion then they should flag not leave everything up to the referee. That is, surely, part of their responsibility.
It is popular and common place to criticise officials but, their decisions can have consequences and it is high time that the EFL and FA looked at standards and started to rectify things.
