Chelsea still in 'turmoil', claims Villas-Boas
After spending time at the club under Jose Mourinho, Villas-Boas returned as head coach at the start of last season but was sacked in March following a string of disappointing results.
His successor, Roberto Di Matteo, has also since been dismissed, despite leading the London side to victory in the FA Cup and UEFA Champions League.
And ahead of his first return to Stamford Bridge, the Portuguese has claimed that little has changed since his time at the club.
"Chelsea is going through the same turmoil of managers after I left. So it makes me a little bit calmer to understand how they work," the 35-year-old said.
"I was another manager that just passed by. I spent three great years on the staff. When I was given more responsibility I wasn’t given time enough, so it means absolutely nothing.
"I have great friends who I don’t want to undermine by what I’m saying. I have great friends there, people who I have a great relationship with and players who gave everything for me so it’s going to be good to see them."
Despite his unhappy spell with Chelsea, Villas-Boas says he was delighted to remain in the Premier League with Spurs, and hinted that his current crop of players are more receptive to his ideas than those at Stamford Bridge.
He added: "It was good to be back in England after last year. I’ve been very well received by everybody, particularly this group of players, whose drive and ambition towards achieving results has been tremendous.
"It becomes easier when the players are willing to commit to your ideas, they need to be able to take something from learning new things and also enjoy learning new things that they can use in their game.
"All the players have received me well and, when you receive that sort of openness, you can create a good environment."
Di Matteo's interim replacement, Rafael Benitez, has endured a frosty relationship with the Chelsea faithful but Villas-Boas is unconcerned by any potential reception he might receive on his return to the club.
He explained: "I have no idea. It makes no difference to me. Hopefully the Chelsea fans are respectful, it should be fine. But if not, it’s fine too."
Spurs sit fifth in the league, going into Wednesday night's clash, three points behind third-placed Chelsea, but will leapfrog Arsenal into fourth with a win.
Despite the uncertainty over their participation in the UEFA Champions League next season, Villas-Boas insists the club are not making different plans for their off-season activities dependant on their place in Europe.
"No, at the moment, our future in order to gain Champions League qualification must be analysed at one direction," he added.
"There cannot be two budgets, for us the objective is always to improve the team."
