It's a shame, especially about Gianluca Mancini who managed to create an assist for Dybala but Gianluca Mancini also scored an own goal. Also, I got some footage, it looks like Sevilla has quite the advantage because the referee doesn't seem to be on AS Roma's side. Because there was a moment when a Sevilla player had a hand ball in the penalty box, but the referee didn't make it a penalty because the hand ball occurred in the penalty box. If so, then Sevilla again and again get lucky because after all, if the referee made a fairer decision then it looks like AS Roma will still win until the end of the match with a score of 1-0 or 2-1.
That's an interesting allegation against the referee, but I have heard that the talks between the referee on the pitch and the VARs are recorded. If the VAR sees a hand ball, the referee would have to be 100% sure about his decision and actively refuse to check it on the monitor. I don't think that happened.
You could also argue that there was a foul before Dybala scored the goal. In the midfield the Sevilla player was held back for a moment by a Roma player with his hands. I wouldn't say it is a foul and the goal was correct, I just wanted to point out that the referee could have made a decision against Roma and he didn't.
This game wasn't really one of those cases where the referee decided who is going to win. There will always be some decisions that the fans argue about, but there have been games that were much worse. In this game I think the referee was ok. They all went all out all the time during the game. It wasn't simple for the referee and yet he kept the control over the game.
