The Selecao squad is full of superstars and Ancelotti is arguably the best man-manager in the world, a man renowned for being able to unite divided dressing rooms and deal with the game's biggest egos.
His tactical acumen is often overlooked for this reason but there is no denying that Ancelotti's laissez-faire approach works well with top talents. The results speak for themselves.
His easy-going and affable personality is also key. Eden Hazard may not be a fan but you'd be hard pressed to find many other players with anything negative to say about Ancelotti.
He endears himself to his charges and he already has a special bond with Madrid's Brazil stars Vinicius Junior, Eder Militao and Rodrygo, as well as former Blancos midfielder Casemiro.
Indeed, Manchester City goalkeeper Ederson has revealed that he has already spoken to his compatriots about Ancelotti and is desperate for him to take over the national team.
"There's a big possibility that he is going to become the new coach of Brazil," he said. "He's an exceptional coach, everyone in his group likes him.
"He's had a victorious career. Just look at his CV. We will know shortly whether he will be here or not."
Ederson even quipped, "We (Man City) will try to eliminate Real Madrid (in the Champions League) so that Ancelotti can come to Brazil as quickly as possible!"
Again, more jokes, but further evidence of just how serious the Selecao are about hiring Ancelotti.
Honestly, he'd be mad to turn them down at this stage of his career.
With a World Cup winners' medal around his neck, Mr. Champions League would have a serious claim on the title of the greatest coach in football history.
