Clarence Seedorf scored a blistering half volley in injury time to give AC Milan a 1-0 win over Chievo and slash Inter's lead to just one point with 10 games left in the Italian Serie A.
It looked like Milan had left their city rivals off the hook for Inter's 3-1 defeat to Catania on Friday after a battling Chievo performance at the San Siro in Sunday's late game.
But veteran Dutchman Seedorf, not known for his goalscoring, had other ideas as he bulldozed through the defence to unleash an unstoppable shot into the far top corner from the edge of the box.
Roma had earlier failed to put extra pressure on stuttering leaders Inter when they were held to a 3-3 draw at lowly Livorno amid a flurry of goals in Serie A.
A Cristiano Lucarelli hat-trick for third-bottom Livorno meant third-placed Roma could only move to within six points of Jose Mourinho's leaders.
"We also have the game against Inter at home so it's not over," Roma's first goalscorer Simone Perrotta told Sky TV on Sunday with his eye on the March 28 clash.
"It's normal you get tired, we've played lots of matches. We've got to rediscover the right physical condition."
Palermo stayed fourth despite a 3-2 defeat at Udinese, who went seven clear of the drop zone largely thanks to goals either side of the break from striker Antonio Floro Flores.
Juventus, enduring a nightmare season, could have gone above the Sicilians into the fourth and final European Champions League qualifying spot but blew a three-goal lead to draw 3-3 with bottom side Siena in Turin.
Alessandro Del Piero scored his 300th and 301st Juve goals inside the first seven minutes with a close-range finish and superb volley before Antonio Candreva thumped in a third.
Siena hit back through Massimo Maccarone and Abdelkader Ghezzal, who then netted a leveller from the spot on 74 minutes after Juve defender Zdenek Grygera fouled Maccarone.
Sampdoria are a point behind fifth-placed Juventus after a 1-1 draw at Bologna with doubts over whether the home side's injury-time equaliser was offside.
Samp's city rivals Genoa, two points further back, enlivened their hopes of Europa League football next season with a thrilling 5-3 victory over Cagliari.
Parma beat second bottom Atalanta 1-0 while famous Roman club Lazio remain in deep trouble, two points above the relegation zone, following a harrowing 2-0 home defeat by Bari.
Fans across Rome will be in despair after Roma twice took the lead at Livorno only for a Lucarelli penalty, after a Juan handball, to level the scores at 3-3 on 71 minutes.
Luca Toni had put Claudio Ranieri's side 2-1 up with a header and David Pizarro's neat finish made it 3-2 before the Chilean hit the post with a penalty.
