I forgot the on-side goal. That was strange because if I understood the whole scene correctly, they didn't show a line in the VAR review on TV. I wondered why they wouldn't do that? But if anything was wrong there, wouldn't they be held accountable after the game as well? It would not be repeated of course, but if Liverpool says there was something wrong or they request the data, I can imagine that the VAR data is stored and has to be available for checks afterwards. Because I agree that the goal was very suspiciously given as off-side and hence taken back. I was like wow, I want to see that line. But they just didn't provide it. If for some reason it was so close that even their computers couldn't draw it, then it should be a goal.
Currently, PGMOL has also actually admitted that Diaz's goal should have been allowed but this kind of thing has happened even though it is now admitted that it was an error from the referee, it still does not restore anything. Liverpool have also responded by providing a statement relating to this matter.
But again this also cannot be changed because it has already happened but it is important for PGMOL because this can be a good lesson and in the end for future matches there are no more human errors like this so as not to harm one of the clubs in a match.
