Napoli coach Rafa Benitez admits Serie A is a unique challenge.

Benitez has won silverware in Spain and England, but has discovered some new problems in Italy.

He told So Foot: "Everyone wants to win the Scudetto, but in Italy if you win a series of games then you're the favourites, then the moment you make one miss-step people eliminate you from the running.

"I am here so that Napoli can make life difficult for others and make themselves respected by the biggest clubs in Italy. We are on the right track to achieve that aim.

"We changed the way Napoli work: physically, tactically and technically. We have made players less tense, less irritable, so that they can give their best.

"The team has a more international profile and players have a much higher market value than when we arrived. We also modified the infrastructure of the club: offices, gyms, meeting rooms, lunch rooms and the rest area where now there are a television and Playstation. We are setting up a specific area for the goalkeepers to train.

"The day I leave Napoli, I will be satisfied to leave my successor a better training ground than the one I found when I arrived."
