The Guangzhou Evergrande boss feels the champions are sitting in pole position to successfully defend their title this term, though, says AC Milan's Mario Balotelli was a top buy
The Bianconeri signed players such as full-back Federico Peluso and striker Nicolas Anelka, while Napoli secured the services of defender Rolando, midfielder Josip Radosevic, winger Pablo Armero and forward Emmanuel Calaio in January.
Furthermore, Inter signed midfielders Mateo Kovacic, Ezequiel Schelotto and Zdravko Kuzmanovic, whereas AC Milan added defender Bartosz Salamon and striker Balotelli to their squad.
"The biggest coup of the window was Milan signing Balotelli, but Juventus remain the team to beat. The other clubs have made some changes, but not enough to change things," Lippi told Tuttosport.
"Napoli undoubtedly strengthened their team in every area and they will fight for the Scudetto with Juve. However, Juventus are still the strongest team for me.
"Players such as Kwadwo Asamoah, who comes back from the Afcon, and Giorgio Chiellini who will return from injury can be seen as new additions as well."
Juventus currently hold a three-point lead over Napoli in the Serie A table.
