I've just watched it loads of times. Unbelievably bad decision. I can't stress enough how utterly poor this decision was.
Firstly, the linesman was correct to flag offside after the ball went in. (Cue vociferous complaining by Fernandez and Rashford, telling the linesman that Rashford didn't touch the ball).
The linesman then calms the United players down. I wonder what he told them. Maybe something like "Don't panic, the goal will stand". Obviously we don't know, but Fernandez's reaction to this brief encounter suggests he knew the goal would stand. Attwell and linesman then have a conversation, and goal is given.
Questions:
1. What did the linesman say to Attwell?
2. What did the VAR say, if anything? Why didn't he intervene and correct this abomination of a decision?
3. Why on earth, didn't the VAR recommend Attwell checks the monitor?
4. Why didn't Attwell ask to see the incident on the monitor to inform his own decision?
This is gross misconduct by all three of them. It should result in disciplinary action. You just know the whole refereeing establishment will close ranks though. Maybe we'll get an acknowledgement and apology.
This has to be a real low point in the already checkered history of VAR. You have to ask yourself if three officials all reaching the same wrong decision is a coincidence, or is it bent?
