Santos have targeted AC Milan defender Alex as the Italian season draws to a close.
32 year old Alex started his career at Santos but left in 2004 to join Chelsea. He has since won titles in England, Holland and France.
Santos do not have the funds to finance a cash deal but are willing to offer Gabriel Barbosa and Gustavo Henrique in exchange for the experienced centre back.
Santos president Modesto Junior Roma is expected to meet with AC Milan vice-president Adriano Galliani on Saturday. Robinho is already expected to join Santos when he leaves AC Milan this summer.
