For 57 minutes it had been going rather well. It was not shaping up to be a perfect debut but considering he had only one training session to get acquainted with his new Chelsea team-mates, Joao Felix had at least introduced some life to an attack that recently looked completely out of ideas.
Then the 23–year-old, who joined on loan from Atletico Madrid on Wednesday morning, produced a moment of recklessness that may not be matched by any other Premier League player for the remainder of the season.
There was a look of shock on Felix’s face as David Coote waved a red card in his face. It cannot have been at the fact he was being sent off, for there cannot be a more obvious dismissal, but at the tackle he had just made.
