Former Italy international Dino Baggio has asked for an investigation to be carried out on substances administered to players of his generation after the recent deaths of Gianluca Vialli and Sinisa Mihajlovic.

Napoli moved seven points clear at the top of Serie A after Sunday's 2-0 win at 10-man Sampdoria, who paid tribute to deceased greats Gianluca Vialli and Sinisa Mihajlovic.

Federico Chiesa dedicated Juventus' late victory over Udinese to Gianluca Vialli following the legendary former Bianconeri striker's death at the age of 58.
