Red Devils full-back Rafael was sent off for a kick on his fellow Brazilian and the Blues man was caught on camera seemingly laughing while on the floor, apparently in pain from the challenge.

He told reporters: "I'm aware that David Luiz is one of the best players in the Premier League, by miles. Miles away of a lot of players, so he is one of the best, without doubt.
"I think that, talking about [Rafael's sending off], we are not talking about Chelsea beating United, doing much better than United in three games.
"David Luiz was laughing because the fans were abusing him and after was the red card, so it was very clear, the timing, but we continue talking about this instead of trying to eradicate the bad tackles that you can see every week.
"I think we are giving importance to something that is not as important as the other things."
