The Nerazzurri defender insisted that his side will keep fighting until the end of the season, while praising the impact of new coach Andrea Stramaccioni on the team
The 3-1 victory at Udinese on Wednesday has left the Nerazzurri just three points shy of third-placed Lazio, who were stunned by Novara 2-1.
"Yesterday's win was important, it was a final for us," Ranocchia told Sky Sport Italia. "We are three points from the Champions League places and we still believe.
"This has been a difficult season, we have changed coaches so many times and we have had so many injuries, but despite all that, we are still there and we will fight until the end."
Ranocchia then took the time to praise coach Andrea Stramaccioni, who has overseen a recovery in the team's form since replacing Claudio Ranieri last month.
"With Stramaccioni we have found enthusiasm, serenity and the right balance again, but no one can say that if he had been here from the start we would not be where we are now," the 24-year-old explained.
"The club have trusted him and he is repaying that with results."
Wesley Sneijder was the man of the match in Wednesday's contest, grabbing a double in what was his first start under Stramaccioni.
"Sneijder has been working really well, he is a champios and now that he is on form again he will help us so much," Ranocchia affirmed.
