The Milan superstar believes the Blues may regret getting rid of his compatriot so soon.
The former Blues boss was responsible for handing his compatriot a first cap for Brazil in 2002 and even selected him for the World Cup-winning squad later that year, although Kaka only played 25 minutes of the tournament.
The Milan midfielder has opined that Scolari would have eventually brought plenty of silverware to Stamford Bridge had he been afforded the time to do so, and suggests the west London club may live to regret their decision.
"I don’t understand how a club that wants so bad to win titles can take such a bad decision as this," Kaka is quoted as saying.
"Just because Chelsea had a couple of bad matches. It was a big mistake. I’m sure, in a few weeks or months, he’ll be coaching an even bigger club than Chelsea."
