The Italian is confident his latest reinforcements will provide the necessary ingredients currently missing within his squad
The Viola have added Anderson, Modibo Diakite, Antonio Rosati and Alessandro Matri to their ranks in a productive month of transfer business in Florence.
And Montella believes they will add vital missing ingredients to his squad as they aim to qualify for the Champions League.
“Diakite has the physicality that we were missing,” Montella said at a press conference ahead of this weekend's trip to Cagliari.
“Anderson can play a little of everything. In our method of play that is ideal. Based on our assessments, we believe he can play around 30 minutes this weekend."
Fiorentina currently trail third-placed Napoli by three points in Serie A.
