AC Milan president Paolo Scaroni has revealed that some of his squad members were still recovering from coronavirus.
Serie A has been on hold since mid-March but Italian Sports Minister Vincenzo Spadafora said on Thursday he was hopeful group training could resume on May 18.
"We have some infected players in the process of recovery," Scaroni told local media.
Scaroni believes Italian football must live with COVID-19 and take an example from the Bundesliga which will restart on May 16.
"We have to get used to living with the virus and this also applies to football," he said.
"It is not possible to stand still until there is zero infection. Basically we can adopt the German formula that provides that those who are sick go into quarantine while their teammates continue."
