Mirabelli is baffled by Milan's struggles to secure Gigio Donnarumma to a new contract.
He said, "Donnarumma is one of the best goalkeepers, in my opinion.
“If you want to keep him, I don't see any difficulties in signing him for another three years. If I succeeded, why can't the champions that are at Milan now?
“What's the problem? Raiola, before I arrived, took over €100m from Milan. I saw the documents."
