For a 22 years old goalkeeper with over 200 appearances in the seria A, Donnarumma is quite the bargain at €60 million, as they are set in the goalkeeping position for at least 8-10 years. I hope Donna excels in Paris, though Keylor Navas might be a problem in the long run, which will be as a result of him(Navas) being automatically demoted to the second choice goalkeeping position except he hands in a transfer request.
