Madrid: Gerard Pique has hit back at Cristiano Ronaldo in the wake of the Real Madrid attacker's claims that the referee favoured Barcelona in the Catalans' 4-3 La Liga win on Sunday.

Referee Undiano Mallenco played a leading role in the enthralling encounter at the Santiago Bernabeu as he awarded three penalties over the course of the game - two to Barcelona and one to Madrid - and sent off Sergio Ramos, prompting Ronaldo to accuse the official of bias toward the Catalans.
