Inter Milan missed the chance to close the gap on Serie A leaders Juventus on Saturday when they could only manage a 1-1 home draw with Genoa.
Esteban Cambiasso's equaliser for the hosts five minutes from time cancelled out Ciro Immobile's superb individual goal as second-placed Inter nudged up to 35 points, nine behind Juve after the champions won 3-1 against Cagliari on Friday.
Genoa remain second bottom on 14 points. Inter's Rodrigo Palacio twice went close early in the second half, first blazing over after finding himself one-on-one with Genoa keeper Sebastien Frey and then forcing a fine save from the Frenchman with a powerful left-foot strike.

A stout Genoa defence easily kept Inter at bay and Immobile hit them with what looked like a fatal sucker punch with 13 minutes left. His fine individual goal saw him ghost past defender Andrea Ranocchia and slip a smart finish under keeper Samir Handanovic.
Cambiasso brought Andrea Stramaccioni's side back into the game with a thumping header but despite late pressure, Inter could not grab the winner and now look increasingly unlikely to take the title from their rivals.
