Ghana's Sulley Muntari dramatically walked off the pitch while playing for Pescara at Cagliari yesterday, after his complaints of alleged racist abuse were met with a yellow card.

Muntari could now face disciplinary measures after deciding, voluntarily, to leave the field seconds before full-time -- a decision that earned him a second yellow card, and then a red, in the 96th minute of the game that his team lost 1-0.

While leaving the pitch he murmured 'Basta!' (Enough) and minutes later, addressed supporters, showing them his arm, shouting: "this is my colour."
