A red card in the game between Chelsea Aston villa was very much avoidable but it was sad Chelsea got the card regardless, I don't know if to blame it on the player or anyone but one thing I think for sure was that it was very unnecessary at that point, there are other big team they will get a red card against and I will see it as worth it to an extent but not for a team like Aston villa.
The red card issue actually destabilized the entire game for Chelsea, from the replay of that tackle, and if it were to be some referee they might have considered that tackle as not a red card offense to be decided as a yellow card offense rather, the tackle in my opinion was not that intentional as they offender went for the ball first before matching on the opponents leg. Anyways, Chelsea did have ample opportunity to have gotten a goal but they couldn't utilize any.
