Atalanta vice-president Luca Percassi hailed coach Gian Piero Gasperini's players after they reached the Champions League final eight.
Their 4-1 win at Valencia means they reach the quarterfinals 8-4 on aggregate.
“What's happening is just extraordinary and anything that comes next is a bonus," Percassi told Sky Sport Italia.
“We received so many messages from all over Bergamo and Italy, not just the football world. This is a difficult time for the city, the region and the country, so we are glad to have given people two hours of entertainment and spectacle.
“There are no secrets to our success, we simply dedicate so much passion, hard work and determination into this club, because the city deserves it. We wanted to thank the city and show them what can be achieved in this difficult moment.
