[....]I also don't know for sure whether the VAR decision for the goal scored by Garnacho was correct or not because after that incident it was Arsenal who managed to turn things around.
What are you trying to say here? Arsenal's last two goals has nothing to do with the disallowed MU goal. If you have a problem with the call then point it out on a technical level and not come of as someone saying MU was robbed of that goal so Arsenal could win. Garnacho was offside by the slightest of margins.
If in the Manchester United vs Arsenal match there are still those who blame the referee's decision, it is a sign that the Manchester United fans are trying to dismiss and do not want to accept the fact that they lost to Arsenal. Even though many of Anthony Taylor's decisions are often controversial, in that fight, in my opinion, he showed fairness and professionalism.
Indeed, many Man United fans do not accept the referee's decision, they should blame ETH's decision, in the bigmatch match using the wrong formation and making ridiculous substitutions. Even if the referee wanted to be fair then the score would also be different because in this match Arsenal also suffered a lot from the referee's decisions, the score should have been 4-1 for Arsenal.
I look at it from a neutral position, Arsenal deserved to win. The game was dominated, when they controlled the ball they were really scary in contrast to Man United who seemed to rely more on counter attacks. Arsenal's creativity also looks more prominent, Oddegard and Martineli are very dangerous.
