Rafael Benitez has spoken to a Swiss newspaper, stressing the importance of Gokhan Inler, Valon Behrami and Blerim Dzemaili.
The Switzerland internationals have become an integral part of the Partenopei midfield under the Spanish tactician.
“All three are very important to Napoli,” he told Blick. “They all give the team a balance, robustness and defensive cover.
“The Swiss national team Coach Otmar Hitzfeld is doing a great job with them.
“They return to Napoli very well prepared in a tactical point of view.”
