Roma ensured they did not lose any further ground on Serie A leaders Juventus as they belatedly returned to winning ways with a 2-1 defeat of Fiorentina.
Rudi Garcia's side had drawn their previous four and after Juve won 2-0 at Bologna on Friday night the gap at the top had increased to six points.

Inter had to be content with a 3-3 draw at home to Parma after Rodrigo Palacio had twice hauled them level.
Palacio (44, 54) cancelled out goals from Nicola Sansone (11) and Marco Parolo (45) and it looked like Inter might even win when Fredy Guarin sent them 3-2 up after 56 minutes.
Sansone (59) quickly replied with his second though to ensure Parma got something for their enterprising performance.
