Milan are "proud" to be part of Serie A but their chief executive Ivan Gazidis believes the European Super League will open up football to billions of fans.
The Rossoneri, along with Juventus and Inter, were among 12 teams included in Sunday's seismic Super League announcement.
Reaction has been sustained and vitriolic, with UEFA, FIFA and the Premier League among those to condemn the plans, alongside Jurgen Klopp and Pep Guardiola – despite Liverpool and Manchester City also being on the initial roster.
Those involved have been accused of undermining their domestic competitions, by foregoing the challenge of qualifying for continental competitions in favour of a closed-shop arrangement.
Nevertheless, Gazidis sought to reaffirm his club's commitment to Italy's top flight in a letter to commercial partners and sponsors.
"Serie A will remain the most important weekend competition in Italy and Milan are proud to remain an important part of the pinnacle of Italian football," he said.
"We're confident that this new competition will capture the imagination of billions of football fans all over the world and will be a new, exciting chapter for the game.
"The Super League will provide value and support to the whole football pyramid with greater financial resources."
Milan are back in action at home to Sassuolo on Wednesday, with solidifying a spot in the top four the priority for head coach Stefano Pioli – irrespective of what that might now mean in the greater scheme of things.
“Milan have never finished top four in the last few years. It would be an important target for us that would prove our growth,” Pioli told a pre-match news conference.
“We have a target, and it's an important one. We are focused on this. We'll see what happens in the future. I repeat, this is not the right time to talk about the Super League."
