That's what it does. Do we think Arsenal would have had that goal chucked off, or not given a penalty? It was a close game, with Spurs being the better side. Therefore, it got "addressed" by the VAR, and obviously a deflated Spurs side conceded the 3rd. The narrative will be that it doesn't matter if the goal should have stood or not, or whether it was a penalty or not, and thus no Saka goal. It's 0-3, so Arsenal deserved to win anyway, right? In any professional sport the margins are small. On another day, Spurs could have been ahead now, but it's corrupted as hell, so it is what it is.
