Wasn't it strange how the soccer associations are trying to fight against racism and here you have a 4th referee who is representing that very same associating league do this?

Atleast in the EPL you see the players
all taking the knee in helping to fight against racism.
Don't think the league in romania does any such thing from where this referee was from.
There will be always some exceptions. The association cannot control the sayings of a referee in a game.
What the association can do right now is to take some measures and avoid this racism attack happen again in the future. The 4th referee should be banned and fined hard.
On the match part, I believe that PSG is going to take the win as this will help them capture the 1st position in the group stage and face an easier opponent in the next stage.
