Mario Balotelli scored a last-gasp winner to help Inter add to Juventus's misery yesterday with a 2-1 comeback win that takes them into the Coppa Italia semi-finals.

The forward thumped in the rebound of a Thiago Motta shot one minute before the end after Lucio's 71st-minute goal had cancelled out Diego's opener.

Inter will face Fiorentina in a two-leg semi-final, the first of which will take place next week.

The match could be Ciro Ferrara's last in charge of Juve as Italian media say the club intend to sack him after a dreadful run of form.

Juventus took the lead in the 10th minute when Inter goalkeeper Francesco Toldo, who looked insecure after getting a rare start with Julio Cesar resting on the bench, let a seemingly inoffensive shot by Diego slip through his arms and the middle of his legs.

The hosts had Juve pinned back for a spell after going behind and were unlucky not to have a penalty for handball by Felipe Melo in the 44th minute.

Juve, without flu-hit captain Alessandro Del Piero and a long list of injured players, withstood the pressure for a spell and had chances at the other end. Giorgio Chiellini hit the post with a header in the 55th.

But centre-back Lucio broke down their resistance by poking in after a Wesley Sneijder free-kick took a big deflection off the wall before Balotelli sealed it for Inter.
