(CNN) -- Defending champions Inter Milan lost the leadership in Serie A as Roma beat Atalanta 2-1 on Sunday to take over at the top of the Italian standings.
Inter have set the pace for much of the season, but Roma are on a tremendous run and now hold a point lead over Jose Mourinho's men with five matches left.
Inter's 2-2 draw at Fiorentina on Saturday left the door open for the capital club who had to fight hard against a stubborn Atalanta side.
First half goals from Mirko Vucinic and Marco Cassetti gave Roma a 2-0 lead, but a Simone Tiribocchi effort for Atalanta in the 53rd minute set up a tense finish.
The other title contenders AC Milan were held to a 2-2 draw at home to Catania and now trail Roma by four points.
But they were grateful even for a point after coming back from 2-0 down with Marco Borriello scoring the equalizing goals after the break.
Claudio Ranieri's Roma were on top from the start at the Stadio Olimpico against the visitors from Bergamo, who are third from bottom.
A mistake from visiting goalkeeper Andrea Consigli allowed Vucinic's long-range effort to dribble into the net and midway through the half the Giallorossi had doubled their lead when Francesco Totti crossed for Cassetti to head home.
Within eight minutes of the second half Tiribocchi was allowed space to score for Atalanta and Julio Sergio had to save bravely from the striker to secure the three points.
Palermo stay fourth, 10 points behind Milan, after coming from a goal down to defeat Chievo with Fabrizio Miccoli scoring a double.
Giorgio Chiellini's first-half header sent Juventus fifth after a 1-0 home win over Cagliari ahead of Sunday night's derby between Sampdoria and Genoa.
