Former AC Milan coach Arrigo Sacchi has paid a glowing tribute to Maurizio Sarri's Napoli.

Napoli and Juventus will clash on Sunday in a title showdown.

"It's a clash between a club with the financial power of Juventus, who bought Napoli's best player [Gonzalo Higuain], but also the strength of their squad and the talent of their Coach [Max Allegri]," Sacchi said on Radio Kiss Kiss Napoli.

“On the other hand you have Napoli, who don't have the history or turnover of Juventus, who lost their best player to Juventus.

“What Sarri has done at Napoli is a masterpiece. He's given them a style of play and is doing something extraordinary, all of the Azzurri have improved.

“With the speed of their play, they've managed to be four points from a team with €40m players on the bench.

“Napoli play an international football, and they can only win if they manage to express it.

“Napoli have already won, what this team has done will be remembered for a long time - longer than [Diego] Maradona's."
