Sir Alex Ferguson has claimed to have once been approached by Chelsea - and has also ruled out stepping out of retirement and returning to Manchester United.
Sir Alex called time on his distinguished career at the end of the 2012/13 campaign after 26 years in charge at Old Trafford, with David Moyes the man chosen as his successor.
Moyes has made not made the most convincing of starts, with United having suffered three defeats in their opening six Premier League fixtures to sit 12th in the table.
It has been suggested that Moyes, who signed a six-year contract after leaving Everton during the summer, could already be on borrowed time, but Ferguson is confident his fellow Scot will turn things around.
In an interview aired on American television network PBS, he said: "I'm not interested in managing again or getting myself worked up about Manchester United's results.
"United are in good hands with David Moyes. He will be fine. He's a good manager.
"You would be throwing your money down the drain if you put any money on me coming back as a manager.
"I made my decision. The timing was perfect. There is no way back for me now. I've got a new life. I want to go to the Kentucky Derby and the US Masters, the Melbourne Cup. I want to visit vineyards in Tuscany and France."
"They used an agent to approach me when Abramovich first took over the club and I said, 'No chance'," he added.
"I always come back to this point - why would you leave?"
