Reports claimed that the Premier League leaders had scouts at Torino's match with Roma at the weekend to watch the Italy international in action.
Despite admitting that he is happy that he could be a transfer target of the Red Devils, the 24-year-old defender has insisted that he will remain fully focused on his team's Serie A relegation fight.
"This obviously pleases me, but right now I do not think about the future. I live in the present. I, just like all my teammates, think only about saving Torino," he told Tuttomercatoweb.
Ogbonna made his debut for Torino back in February 2007.
