Lecce came from a goal down to beat Siena 4-1 in Puglia on Sunday to boost their hopes of beating the drop this season.
Lecce remain two points from safety but with Siena the team occupying the final survival position it was a crucial success.
Cristiano Del Grosso had given the visitors the lead with a back post volley from six yards but Lecce came roaring back.
Luis Muriel equalised before the break from close range following a melee at a corner.
And the Colombian then went on a mazy run, jinking his way into the box before earning a second half penalty.
Muriel did flop easily to the ground but having grabbed the forward around the waist with both arms, Alessandro Gazzi could have no complaints, protest as he did.
David Di Michele converted the spot-kick before Lecce added two late goals.
Another Colombian Juan Cuadrado went on another eyecatching run on the counter-attack before cleverly chipping goalkeeper Gianluca Pegolo while Davide Brivio scored his first ever goal in Serie A with a rasping free-kick.
