He set his stall out early on when not cautioning Felipe for a terrible challenge on Foden. Generally I liked his approach, he wasn't falling for diving and tried to keep the game moving, but I don't think he ever at any point had it under control and he looked out of his depth unfortunately. There's a time and place for playing loads of advantages and not giving soft free kicks, and this game absolutely wasn't it.
For the flare up at the end I saw the secondary challenge on Foden by Felipe real time and thought it was borderline red, but certainly a caution. For whatever reason the referee missed it, but it looks like the 4th official went to talk to him and tell him to give a second caution. Savic appeared to headbut a player in the melee, and he certainly pulled Grealish's hair, both of which should be red card offences, can understand the on-pitch officals not seeing this, but what was VAR doing?
Disgraceful behaviour yet again by Athletico and the authorities really need to take action against them. Every decision, no matter how minor, they have five or six players immediately surround the referee, that isn't down to the players and rather that is absolutely coached. Likewise the technical area, Simeone has a different backroom team now but the behaviour is the same as it was with the old one. Only one common demoninator.
