David Trezeguet believes Juventus can improve under new coach Massimiliano Allegri.
Allegri succeeded Antonio Conte over the summer.
"Juventus are still the favourites in Serie A, as they have a great squad and signed some very good reinforcements," Trezeguet told Tuttosport.
"They changed Coach, but that will not affect their winning mentality. In fact, it could offer new solutions.
"Roma are improving, Rudi Garcia worked well, but Juve still have something more."
