Sergio Busquets has predictably emerged as the pantomime villain in the fallout from Barcelona's 4-3 Clásico win at Real Madrid.
Busquets, one of the most loathed footballers on the continent thanks to his theatrics which led to Internazionale midfielder Thiago Motta's red card at Camp Nou in 2010, appeared to rake his studs across Madrid defender Pepe's head in the first-half.
Pepe was on the deck, along with Barça's Cesc Fàbregas, after the two collided innocuously during the outstanding flare-up on another tetchy night between Spain's greatest sides.
Busquets avoided censure three years ago after Real accused him of racially abusing left-back Marcelo during the teams' Champions League semi-final first leg.
Madrid argued the Spain midfielder called Marcelo "mono", which translates as "monkey".
Uefa charged Busquets but later cleared him of any wrongdoing.
