Atalanta made the request as their stadium is currently being renovated to meet UEFA standards.
Despite being initially hesitant, the Rossoneri are now in agreement with Inter and Milan’s city council over letting the Dea use the arena.
“We can confirm that we accept Atalanta’s request to be able to play their Champions League home matches at San Siro,” they told ANSA.
“Our decision comes in compliance with the positive opinion of Milan mayor Giuseppe Sala and after having understood the strong desire of the Bergamo club.
“We believe this opportunity is beneficial not only for Atalanta but also all of Italian football as it is inspired by important values such as the sense of hospitality, respect and ‘fair play’.”
Atalanta previously used Sassuolo’s Mapei Stadium for Europa League home games in 2017-18, but the 80,000-seater venue became an option after Milan pulled out of the competition.
That means they can now look forward to their first-ever Champions League campaign being played in part at San Siro, which is just 60km away from Bergamo.
Atalanta captain Papu Gomez has thanked Inter and Milan for the ‘honour’ of letting his club use San Siro, but ultras of the city rivals are furious.
“Unfortunately, the Champions League won’t be played at our stadium,” Gomez wrote on Instagram.
“For this reason, on behalf of my teammates, we want to thank Inter and Milan for welcoming us to their glorious stadium…
“For us it’s crucial not to make long trips, especially in such a demanding competition. It’ll be an honour to play San Siro and we’ll give the best of ourselves. Thank you so much.”
However, in a lengthy statement, the Curva Sud slammed the decision.
“In the football we love, this request would’ve been returned to sender with a good, long laugh. Percassi’s request offends us Milan fans. San Siro is our home.”
That was preceded by a similarly-critical post from Inter’s Curva Nord ultras.
“A wicked choice, absurd, dictated by interests and one that tramples over all logic.”
