Dzemaili helped Napoli to an exciting 5-3 win.
"For me it was a special game," he told Blick. "For the first time in my career I was able to score a hat-trick.
"I managed to get it against my old club as well, and help my current team win after so many many games where we had some problems.
"Without this small crisis, we would surely be in the running for the title."
