Sampdoria completed a league double over Serie A champions Juventus with a 3-2 win in Genoa.
The Blucerchiati, who beat the Old Lady 2-1 in Turin on January 6, fell behind to a Fabio Quagliarella strike midway through the first half.
However, Delio Rossi's men fought back to go in level at the break courtesy of a Citadin Eder penalty kick.
Lorenzo De Silvestri completed the turnaround on the hour mark, before Mauro Icardi made sure of the points with a simple tap-in.
Emanuele Giaccherini pulled one back in stoppage time, but it was not enough to maintain Juve's six-game unbeaten run.
Sampdoria are the only team in Serie A who have not been beaten by Juventus this season.
