Former Manchester United defender David May blasted Chelsea stopper David Luiz for getting Rafael sent off.
Ryan Giggs was fuming at Oscar for waving an imaginary red card, which sparked a melee between the two sets of players.
In addition, Luiz was pictured rolling about, seemingly in agony, but in actuality with a broad grin on his face.
Speaking on MUTV, former United defender David May said: "It is a joke. Players are cheating. It is disgusting."
