Inter Milan reignited their faint hopes of winning the Serie A title by thrashing bottom-place Spal 4-0 on Thursday.
Antonio Candreva, Cristiano Biraghi, Alexis Sanchez and Roberto Gagliardini scored to help the Nerazzurri move one point above third-place Atalanta, and to within six points of league leader Juventus with five rounds left.
Spal remain rooted to the foot of the table, 11 points from safety.
Antonio Conte's Inter dominated from the start but took until eight minutes from halftime to break the deadlock when Candreva fired home following a pinpoint assist from Sanchez.
Biraghi doubled the visitors' lead 10 minutes after the resumption and he set up Sanchez five minutes later with a cross from the left.
Gagliardini had the easiest of finishes in the 73rd to add to the scoreline when he prodded in Ashley Young's cross.
"It was important to win this game," Inter defender Biraghi said.
"We knew that SPAL were in trouble, but it is always hard to meet these kind of teams. We knew that after taking the lead we could clinch the win. We are second, we look at the top and continue on our path."
Elsewhere, Torino beat fellow strugglers Genoa 3-0 to boost their hopes of avoiding relegation.
Bremer, Sasa Lukic and Andrea Belotti scored to help the hosts move eight points clear of the bottom three.
Genoa remain in trouble, sitting only one point above 18th-placed Lecce.
The home side took the lead in Turin on 32 minutes when Brazilian Bremer headed in a corner from Simone Verdi.
The Torino defender had earlier headed a similar chance narrowly wide.
Lukic was brought on for Verdi in the 67th and he doubled "Il Toro's" lead nine minutes later when he curled into the top corner from long range.
Belotti capped a good night for the hosts in the final minute, scoring for the seventh straight match, with a powerful shot after intercepting a poor back pass from Genoa forward Goran Pandev.
