Conte was axed by Chelsea earlier this summer after two years with the Blues.
He won the Premier League in his first campaign and the FA Cup last term.

Spokesman Paddy Power said: “We’ve been inundated with bets on Antonio Conte to Man United all day, and have been forced to butcher the odds on him taking over from his arch-nemesis.
“We’re sure that he’d love the opportunity to show Jose up, plus, it’s gotta be better than sitting around in your pants all day and watching Jeremy Kyle.”
