Walter Mazzarri's side made a disastrous start to 2014 but have begun to turn things around in recent weeks
Inter can pile further pressure on Cagliari coach Diego Lopez with a third straight Serie A victory when the sides meet at San Siro on Sunday.
Walter Mazzarri's men have been in good form this month, bouncing back from their 3-1 defeat to champions Juventus to record victories over Sassuolo and Fiorentina.
Their latest win saw them close the gap between themselves and Vincenzo Montella's fourth-placed men to five points.
While Fiorentina and Inter currently occupy the two Europa League spots, the Viola travel to Parma on Monday, so victory for the Nerazzurri would allow them to pile the pressure on Vincenzo Montella's side.
Cagliari have a reasonable recent record against Inter, though, avoiding defeat in each of their last four games, although three of these have been draws.
However, if they are to take anything from the game, they will need to arrest this season's woeful away form.
Lopez's side have failed to win a game on the road all season, scoring just four goals on their way to picking up five of a possible 33 points.
