The Tottenham manager lasted less than a year in the Stamford Bridge hotseat, and has criticized owner Roman Abramovich over the sacking of his successor Roberto Di Matteo
The Portuguese was appointed by the Blues ahead of the 2011-12 season but was sacked and replaced by his assistant Roberto Di Matteo after just nine months.
And, after Di Matteo suffered the same fate this term - despite having led the west London side to its maiden Champions League triumph - Villas-Boas has hit out at the club's hierarchy.
"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."
The former Porto boss was keen to underline his happiness at Tottenham, however, insisting Spurs are on track for a successful season.
"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."
