The 29-year-old has been a remarkable success at Napoli, playing a key role in their 2024-25 Scudetto win under Antonio Conte.
His fine form has seen several rumours regarding a potential return to Man United circulate, although he remains under contract at Napoli until 2028.
Tuttomercatoweb recently reported that he and his girlfriend, Cam Reading, want to move to England "as soon as possible."
Speaking in an exclusive interview with Corriere dello Sport, McTominay said: “My agent hasn’t spoken to anyone about my future. He only talks to the club and me.
"He hasn’t said anything to the newspapers. I’m extremely happy here, and as for me, I’m a Napoli player; that’s all I think about. The future is very important, and I could see myself at Napoli for a long time.”
