Jose Maria Callejon believes that Napoli have showed their ‘winning mentality’ after beating Roma on Wednesday.
The Partenopei reached the final of the Coppa Italia after coming from behind to beat the Giallorossi 5-3 on two legs.
And the Spaniard has claimed that the Stadio San Paolo outfit have demonstrated their quality with that win.
“Against Roma we have shown our strength and winning mentality,” he told Sky Sport Italia.
“On Sunday against Sassuolo we have to show the same ability. It’s an important game for us and we want three points.”
The former Real Madrid man then commented on Gonzalo Higuain’s impact and possibly going to the World Cup with Spain.
“As far as I’m concerned, Gonzalo is the most decisive player in Italy.
“The World Cup? Yes, it’s a dream of mine to play there with Spain.”
