Vincenzo Montella's side look set to sign the midfielder from Lazio but there are doubts over the future of Suso, who has been linked with Tottenham
The agent of Lucas Biglia says the midfielder will complete a transfer from Lazio to AC Milan on Friday.
The Argentina international has long been linked with a move to San Siro and reports emerged on Thursday to suggest a deal had at last been agreed between the clubs.
Enzo Montepaone later confirmed the 31-year-old is due in Milan on Friday to finalise the terms of a deal that will reportedly cost the Rossoneri €17 million.
