According to SportItalia, Inter intends to send one of the players to Lazio in order to convince Lazio President Claudio Lotito to send Keita Baldé the opposite direction with a lower pricetag. Now that Eder is staying, Stevan Jovetic, who still hopes for a return to Sevilla, could be that player and Jovetic himself seems to be open for such transfer.
