The ex-Roma coach is in talks with Juve today about replacing Igor Tudor following his axing on Monday.
Sabatini told La Gazzetta dello Sport: "Spalletti's style is generous, beneficial to the attackers.
"(Mauro) Icardi averaged nearly a goal per game at Inter, as did (Victor) Osimhen. Luciano always arrives in the box with five or six players and precise passing lines. (Jonathan) David will return to scoring at Lille's pace. And (Dusan) Vlahovic will shine."
On Kenan Yildiz, Sabatini was also bullish.
He said, "He's a fabulous talent, young but already decisive at the highest level. Yildiz can be what (Khvicha) Kvaratskhelia was for Spalletti's Napoli side during their Scudetto triumph.
"Not so much in terms of his characteristics, which are different, but in terms of his impact on the team and on matches."
