Jose Callejon has heaped praise on the two Napoli Coaches he has worked under, Rafa Benitez and Maurizio Sarri.
The 29-year-old's Spanish compatriot Benitez was responsible for signing him from Real Madrid in 2013, and he has since enjoyed a successful period at the San Paolo.
"I was very happy [at Real Madrid], but I felt I needed to take a step forward in my career and be a first team regular," Callejon told Spanish daily AS.
