Inter Milan hero Walter Zenga is impressed by Luciano Spalletti's team.

Spalletti's Inter remain unbeaten in Serie A this season.

Zenga said: "They're playing like a big team.

"But the only ones who say they want to win the title are still the Juventus players. Every coach has his own strategies and probably Spalletti does not want to give too much responsibility to his kids."

Asked about Gigi Buffon's Italy heir, he added: "(Genoa goalkeeper Mattia) Perin is a goalkeeper I always liked, after Buffon it is in his hands and in (AC Milan keeper Gigo) Donnarumma's hands."
