I'm 99% certain he was always going red for the initial tackle. The ball wasn't even close to being playable and the defender has intentionally put his studs down his achiles. Might be yellow in the Premier League, but European referees have always taken a hard stance when a player is taken out when the ball isn't playable, something I fully support. If the ball isn't playable then you are just intentionally kicking an opponent, and that is VC.
