I heard rumors that Mats Hummels will be a target for several Serie A teams from Milan, Juventus and Roma. After parting ways with Dortmund, he became a free agent and this is a rare opportunity that other teams will compete for. However, of the three teams, the closest is Milan and looks like they will get the services of a good center back.

Despite being 35 years old, to be honest, Mats Hummel's performance is still very good at European level and his decision to part ways with Dortmund was purely an agreement from the club owner. So of course this is not related to performance and Milan would be very lucky to be able to sign him for a season or more.
