The Portuguese tactician was sacked by Blues owner Roman Abramovich last season after just nine months at the helm before taking the Spurs role in the summer.
He believes that the Stamford Bridge club only look to the short-term and have no plans for the future.
"There are no plans at Chelsea," Villas-Boas told The Sun. "It's results that rule. There are times in football when it's easier to replace the coach, but when you embrace a project you believe in people.
"There was a commitment from Abramovich and his word was given, yet there was a premature departure."
And Villas-Boas added that he feels things at Tottenham are going well following the first half of the campaign.
"We're achieving what we've been asked to achieve," Villas-Boas added. "We're still in the Europa League and third in the Premier League.”
