Inter Milan ended a difficult week on a high with a 2-0 win over Chievo which lifted them back up to second in Serie A ahead of Napoli, who travel to Bologna on Sunday.
Goals from Esteban Cambiasso and Maicon in the second half earned Leonardo's side all three points to restore faith in their title challenge after heavy defeats to AC Milan and Schalke over the last seven days.
They now trail league leaders AC Milan by two points while Chievo are still not safe from relegation, with a six-point cushion over the bottom three which could be reduced to three on Sunday.
Udinese's hopes of playing in the Champions League next season were dealt a further blow with their second consecutive defeat, a 2-1 reverse at home to Roma.
A penalty from Francesco Totti in the 57th minute put the Giallorossi in front, but Antonio Di Natale levelled two minutes from time.
However, Totti's second - with the final kick of the game - broke Udinese's hearts and gave Roma all three points to get them back into the hunt for a top-four finish.
