Referee Tony Chapron became the pantomime villain of Paris Saint-Germain's 1-0 win at Nantes on Sunday, after responding to an accidental collision with Diego Carlos by kicking the Brazilian and sending him off. In injury time and with PSG on the counter-attack, Chapron stepped across the backtracking Nantes centre-back Carlos and tumbled to the floor.
