Due to the Coronavirus outbreak, football has been brought to a halt. However, although it could take a while before the games are back on, the teams could potentially start training again after May 4th.
As reported by MilanNews.it, AC Milan are working hard to be fully prepared for this scenario. Of course, Milanello would be the only place for the club, as it has everything they need (pitches, gyms and accommodation for players and staff).
In other words, it would be a very strict training retreat, with the players remaining at the training ground as well as the staff. So far, though, there has been no official communication from the league on the resumption of the season.
Furthermore, the Rossoneri are yet to bring home the players that are abroad. Once they return, it remains to be seen what the quarantine process will be. Therefore, the situation remains uncertain and very complicated.
