Zlatan Ibrahimovic has been out due to injury and since then the Rossoneri's coach Stefano Pioli had to field Rebic as a centre-forward a few times then settle on Rafael Leao who had more success in that position and role.
According to the newspaper QS, AC Milan pays attention to the vice-ibrahimovic matter closely. The source publishes a photo of Belotti and writes that Torino's 27 year-old striker is in the viewfinder of Paolo Maldini.
It can be logic that the Milan management could be thinking for a backup to replace the Swede champion whenever he is not available.
