The Spain international joined the Rossoneri on a two-year loan deal from the Blues just before the close of the summer transfer window.
But Mourinho has explained that, even though the striker failed to nail down a regular starting berth during their time together at Stamford Bridge, he holds the 30-year-old in the highest esteem and, therefore, would have loved to have seen him join Milan's city rivals.
"I'm an Interista and I would have preferred if he'd gone to Inter," the Portuguese stated at a Uefa coaching seminar in Nyon. "However, I hope that he does equally well at Milan.
"What I can say about Fernando is that as a person and a professional, there is nothing to doubt about him.
"He's a fantastic boy and a great professional. However, he needed a change of scenery."
Torres joined Chelsea for £50 million in January 2011 but never managed to justify his then British record transfer fee, netting just 20 goals in 110 Premier League games for the Blues.
