VAR is still being judged by humans, which is why it still leaves a lot of problems in many football matches. For the club that is disadvantaged, of course it is very annoying, but the opposite is true for the club that benefits.
Maybe it is like that, because I also feel that the result is already determined and only the referee and the person involved will be punished. Points will remain the same and the match will not be repeated. But it was still Barcelona's loss.
Whatever happens, the referee is still the leader in the course of a match and VAR is an artificial tool that can help the referee to see footage of particular incident during the match, after all, VAR is tool that has been authorized by FIFA.
When the result has been decided, whatever the team at loss like Barcelona will do will not affect anything and rematch will never take place.
Problems like this often occur in various leagues and competitions, but the final solution will never be as expected by those who suffer losses.
So basically whatever efforts the Barcelona president makes will not change anything.
Talking about Lamine Yamal, Barcelona must be prepared to lose this talented young player because it is reported that PSG has prepared fantastic funds to buy this player.
Regarding Yamal, he is Barcelona's best asset should he stay. Remember there is a release clause that is quite expensive for Yamal if not mistaken €1 billion. If Yamal leaves, it will make Barcelona even weaker.
Of course Lamine Yamal is valuable asset for Barcelona because he is still very young and has quite great talent, he really has great potential and this is why Barcelona uses him quite often as an important player.
Although he is not the only player who can join big team at very young age.
By the way, PSG seems to be still trying to bring in Lamine Yamal and PSG is preparing 200 million euros to be able to get Lamine Yamal.
