Donnarumma happy with reception
The win sealed a 3-0 aggregate victory and put Milan in the hat for today's play-off round draw.
Speaking following the game, the goalkeeper said that he was happy with the reception he received, given his contract travails over the summer.
The youngster told Milan TV: 'I thank the supporters for the welcome and cheers they gave to me.
'I didn't expect it, but I am happy at the way they greeted me and promise I will always give everything for this jersey. They know I am Milan's first fan.
'For me it is as if nothing happened. I have always been myself and I try to help my team-mates the way they help me.
'We are working well and the credit for the two clean sheets over two legs is down to the whole team. I thank my team-mates.'
