Dutchman Koopmeiners, who has also courted interest from Napoli and Juventus, told De Telegraaf his future lies away from the Nerazzurri.
"I have told the club that I want to move next summer. But something really interesting must present itself in order to leave Bergamo," he said.
"Already last year there was concrete interest from Napoli. I also read about interest from Juventus and some Premier League teams.
"For some clubs in England, I will also put up with the rain! In Bergamo we had a wonderful time, I hope that Atalanta will collect a nice sum from me."
Koopmeiners is in his third season with Atalanta after joining the Serie A side from AZ Alkmaar in 2021.
At international level, he has 20 caps for the Netherlands.
