"We were down and weren't managing to give 100 percent but then we spoke at half-time to change the spirit of the team and that's what happened."
Coach Edy Reja said his team had needed a kick-start following their losses to Inter Milan, Juventus and Udinese.
"There was some disappointment during the week because there was the fear that we wouldn't achieve our objective of qualifying for the Champions League, but we have to believe," he said.
"At half-time I said if we kept playing like that we risked throwing away an entire season. The players reacted, they were committed and I congratulate them", he added.
"We have to believe right to the end. We've done what we had to do and I hope today's win will inspire us. We have 63 points and we hope that at the end we'll have at least qualified for Europe."
