Former AC Milan midfielder Demetrio Albertini believes Sunday's showdown between Napoli and Juventus will be decided by mental strength.
Juve's stumble against Crotone has opened the door for Napoli to get back into the battle for the Scudetto.
“Style has always been Napoli's strong suit and they always played well, even in defeat," Albertini told Radio CRC.
“It's a fascinating campaign and Napoli deserve to be up there. Juve are accustomed to winning and that may well be the difference with Napoli.
“The four-point lead gives Juventus the option of playing for the draw as well as victory, whereas Napoli absolutely need to win.
“The strongest side doesn't always emerge on top, but victory usually goes to whoever has the most belief. In these 90 minutes, Napoli will be under pressure at times, but must never play with fear."
