Antonio Cassano struck the only goal of the game to hand Samp a crucial three points.
"The team is doing really well, and we do not want to give up the fight for Europe. We will try our utmost," Pazzini said.
"Cassano scored a fantastic goal, in typical Antonio Cassano fashion. He is a champion, and a very important player for us. We are glad that he has recovered from his injury, and he will help us throughout the remainder of the season.
"The team has gotten over this difficult period, and now we can aim to do well."
