Internazionale's poor run of form under Rafael Benítez continued today with a 2-1 defeat at Chievo, where Samuel Eto'o got away with an apparent Zinedine Zidane-like headbutt.

Inter's president, Massimo Moratti, gave Benítez his backing after last weekend's derby defeat by the Serie A leaders Milan, but another loss has left the Spaniard exposed with the champions now in sixth place, nine points off top spot.

Eto'o was not cautioned by the referee for his headbutt on the Chievo defender Bostjan Cesar, but the Cameroon striker could be punished retrospectively. He scored Inter's consolation goal late on after Sergio Pellissier and Davide Moscardelli put Chievo two up.

Second-placed Lazio also lost ground on Milan after a 1-1 draw at Parma that left the gap at three points. Milan beat Fiorentina 1-0 on Saturday.
