Arsenal were unlucky to have that conceded goal against Newcastle United even VAR engaged in analysis before the referee made his decision to accept the goal for Newcastle United. It is a controversial situation and I believe it is not a goal but the match ended, VAR and referee made a wrong decision which can not be changed.
Even with VAR, mistakes can be made and I really dislike VAR. I love the traditional style without VAR because it makes matches more emotional without long breaking time for VAR checking.
I believe that yes that was bit unlucky for Arsenal but we need to move on. Arteta ranting about it in post conference or us having an opinion won't change that decision. We need to move on and try to score as much as goals as possible and as early as possible in the game. Newcastle were tough to break but I think given our quality in the squad , we also had to score some goals early. VAR is a very bad introduction to the world of football but now we can't change it. Having any kinds of opinion from coaches or staffs won't change it either.
