Hernan Crespo gave Inter the lead after three minutes with an easy tap-in after Esteban Cambiasso's shot was parried by Stefano Sorrentino into his path.

Michele Marcolini equalized on 27 minutes when his thunderbolt went past the motionless Julio Cesar.

Mario Balotelli restored Inter's advantage four minutes past the hour mark with a right-footed shot from the edge of the area.

Chievo's Luciano secured a share of spoils on 73 minutes after capitalizing on a defensive blunder.

Inter could have wrapped up their fourth successive title had they won and nearest challengers Milan lost to Juventus later on Sunday.

Second-placed Milan can narrow the gap with Inter to five points with three matches to play if they beat Juve.
