Musah's future has been speculated about throughout the summer, with Napoli, Nottingham Forest, and Crystal Palace all suggested to have had interest in the American midfielder. As recently as last week, the 22-year-old was adamant he wanted to stay with AC Milan.
"I am happy at Milan," he told ESPN FC. "It is a great club. I'd love to win some great things here. It felt really nice winning the Super Cup last season, so I'd love to win more things. This is what we're expected to do here. I am just happy here, and I am looking to work hard and be a main player in the team."
Atalanta's interest in Musah persisted. If the move goes through, it would allow Musah to get a much-needed fresh start, while also staying in Italy - a reported preference for the former Valencia standout. Ivan Jurić, Atalanta's manager, plays a formation that could better suit Musah's strengths.
During his two years at Milan, Musah has struggled to get consistent playing time and roles under four managers.
