Ciccio Graziani has questioned Edin Dzeko's value at Inter Milan.
The veteran centre-forward joined Inter from Roma over the summer as a replacement for Chelsea signing Romelu Lukaku.
Former Torino star Graziani said: "He no longer has the instinct of the killer, the nose for a goal.
“The Nerazzurri have lost Lukaku and the Bosnian cannot replace him in terms of reliability.
“In Serie A you pay less for his absence, in Europe, you realize the importance of the Belgian's farewell."
