Chelsea boss Antonio Conte commented on the all-in brawl at the end of victory at Manchester City.
It saw two City players sent off after a bad Sergio Aguero challenge. Aguero and Fernandinho saw red.
"The final [stage] wasn't good. I hope only Luiz is not injured after this tackle. It's very difficult to explain this final part of the game. I support the referee. It is important that the referee whistles and we 'finish'.
"I'm happy because I always tell my players to be focused on the game on the pitch, and always to keep calm. It's normal when you play these big games it's not easy to keep calm in every single moment, but I'm pleased because all my players tried to keep calm," said Conte.
