Milan want to bring Fiorentina playmaker Adem Ljajic to San Siro, but first have to sell Robinho.
The Brazilian attacker has been strong linked with a move away from the Rossoneri this summer, with Santos the most likely candidates for his signature.
However, the President of the Brazilian club admitted earlier this week that they would not break the bank for the former Real Madrid man.
Massimiliano Allegri's side are looking for around €8m for Robinho, and would hope to reinvest that sum into the purchase of Ljajic.
The Serbia international has become highly sought-after following an impressive campaign last time out for the Viola, with his agent reportedly trying to broker a deal with Atletico Madrid.
