Former Fiorentina star Daniele Bertoni has urged his old club to go for Olympiacos ace Nery Castillo.

Bertoni, who is doing media work at the Copa America, declared: "For sure, one of the players who is putting his name forward is the Mexican forward Castillo.

"Fiorentina should think about this player for their attack. The Viola have just lost a great forward in Luca Toni and need to strengthen this area."
