Italian club AC Milan are in negotiations with Schalke to sign 27-year-old central-defender Matija Nastasić, according to Di Marzio.
The Bundesliga club would be willing to allow the Serbia international to leave on loan with an obligation to buy, having played just 16 league games for Schalke last season.
Even with the departure of Weston McKennie to Juventus, Schalke find themselves in a dire financial situation and must sell before bringing in further signings.
