Donnarumma made his Azzurri debut last week.
“It was a huge thrill to be called-up to the national team," Donnarumma told Sky Italia.
“I thank Ventura for the opportunity. As for Buffon, he gave me lots of advice in training, he told me to have fun. It was fantastic."
Donnarumma was also asked about his future, and assured he'll be staying at Milan.
“I'm just thinking about Milan and training well every day."
