Reports in Serbia claim Genoa are very close to agreeing a deal for Partizan Belgrade striker Cleo.
The 25-year-old Brazilian has scored five goals in eight games in Europe this season.
According to Blic, Genoa have a verbal agreement with Partizan to sign the player for €4.5m.
However, the transfer appears to have stalled after Genoa failed to give the necessary financial guarantees.
Partizan believe Genoa are being tactical in an effort to get Cleo's price reduced.
If the transfer does go through, Cleo would replace Luca Toni who left for Juventus earlier this month.
