Roma 0-0 Cagliari
Roma wasted the chance to go back to the top of Serie A as they were held to a goalless draw by Cagliari.
Juventus had gone top of the table at the weekend and Roma were unable to find a way past Cagliari goalkeeper Vlada Avramov.
Avramov denied Gervinho, Maicon and Alessandro Florenzi, while former Arsenal striker Gervinho hit the post.
Roma boss Rudi Garcia was sent to the stands late on after an altercation on the touchline.
Garcia said: "Maybe I was just too involved in the game.
"This was an unexpected result. People often say if you can't win, the next best thing is not to lose.
"But we had a really good game, created a lot of chances and in the end showed that the best player on the park was their goalkeeper."
Roma started the Serie A campaign with 10 straight victories, but have now failed to win their last three matches, drawing them all.
They remain unbeaten but are a point behind Juventus.
