Napoli forward Jose Callejon has claimed that the race for the Serie A title will be very close.
The Spaniard joined Napoli from Real Madrid in the summer transfer window and has been impressed by the quality of teams in Italy.
Callejon insists that his teammates are working hard to maintain their good start to the season and challenge for silverware.
"Serie A is a great league, as there aren't just two teams in the running for the Scudetto," he told reporters. "We have some strong rivals in front of us and we're interested to see what happens when Juventus and Roma go head-to-head.
"Football is like a religion here and every day people stop me in the street, asking me to win it all.
"We've got to keep our feet on the ground, as we started the season well, but now we must maintain the right balance to understand what our real objectives are."
Callejon has scored seven goals in 14 appearances for Napoli so far this season.
