Santos president Modesto Junior Roma will meet with AC Milan vice-president Adriano Galliani on Saturday.Santos are interested in Milan defender Alex, but do not have cash to table an offer to the Rossoneri.
Instead, Santos are willing to discuss a swap deal, involving striker Gabriel Barbosa and Gustavo Henrique.
Striker Gabigol and defender Henrique are both regarded by Milan scouts and a deal could be thrashed out this weekend.
Milan have already agreed to release Robinho, currently on-loan at Santos, from his contract this week.
