Inter Milan director Bedy Moratti has claimed Jose Mourinho is "going to Manchester" amid strong speculation linking him with United.
Mourinho is in Milan this weekend to watch his former side take on Sampdoria and to visit ex-Inter president Massimo Moratti and his family.
Sources told ESPN FC earlier this month that Mourinho, who is without a club after leaving Chelsea in December, was increasingly confident he would secure the United job.
Bedy Moratti, Massimo's sister, was filmed leaving a lunch meeting with Mourinho and told Calcio Mercato in a video interview: "It was pleasant. He's still fantastic. He's been missed on a human level.
"Now he's happy -- he's going to Manchester and he's well."
Bedy Moratti had previously been a board member at Inter and still holds a role as honorary president of Inter Club coordination following Erick Thohir's takeover in 2013.
The Moratti family retain a 29.5 percent stake in the club while Bedy's sister-in-law Milly sits on the advisory board.
On Friday, Mourinho insisted that he was only visiting and not seeking to replace coach Roberto Mancini at the San Siro, but a day later he could not rule out a future move to the club he coached from 2008-2010.
"Moratti will always be my president," Mourinho told Sky Sports Italia. "Could I return one day, why not? I returned to Chelsea, so why not back to Inter too?
"As I said today, I just want everything to go well for [president Erick] Thohir and Mancini at Inter."
Mourinho, who also watched Borussia Dortmund play earlier this month, said it was important to him to keep up business relationships.
"What does it mean being here? Coming back home, family, a rapport that remains very close to them even if I've been away almost six years," Mourinho said. "This means coming back home and it feels like it has been six days more than six years.
"The greatest thing about football, more important than results or victories, is the human rapport and friendship that remains."
Massimo Moratti also spoke to journalists after the lunch meeting and said they had reminisced about Mourinho's final season in 2009-10, when the club won Serie A, the Coppa Italia and Champions League.
"It was a meeting between friends, with plenty of memories," he said. "We didn't talk about [him returning to Inter in future]. He's thinking of his future while Inter are not looking for a new coach. We relived 2010 and other memories from the past. It was an idea we had a while ago [to meet up].
"A year ago, we thought about having a reunion with all those who had won the Champions League in 2010, and then we arranged to meet this Saturday. Inter fans still love him."
Asked if Mourinho was joining Manchester United, he replied: "I'm not sure. I don't know if he wants to say."
Mourinho has claimed his next destination is uncertain, but he has been strongly linked with the United job as Louis van Gaal comes under increasing pressure following disappointing performances and results.
"My next club? I really don't know," Mourinho said in a statement released to La Stampa on Friday. "One thing is certain -- I love football and I will return on the fields with the same passion and ambition as always.
"Right now I have respect for every coach and every club. I'm not looking for a club; it is the clubs who seek me."
