No. The ref is correct. He should let the play continue. A red card incident doesnt imply it has to be stopped.

I would say the whole incident was a tough call for ref but he was correct. Ajax players committed two fouls that are worthy for yellow card. The play was advantage to Chelsea so it should be continued. The second foul was inside the penalty area so it’s a penalty.

Ajax fans felt unfair. I can understand that. But to me it really looks fair to me.
