Andre Villas-Boas admits his promising start to life at Tottenham is down to learning the mistakes of his time at Chelsea.
The Portuguese manager lasted less than a season at Stamford Bridge after falling out with senior players and suffering a prickly relationship with the press.
He was given the chance to resurrect his career in England at Spurs last summer and despite losing Luka Modric and Rafael van der Vaart, has led side to fourth in the Premier League and into the knockout stages of the Europa League.
"What we are doing nowadays at Tottenham with my staff is a reaction toward Chelsea, an echo to the mistakes we did," he told France Football.
"Everything we did there was not wrong, but we could have done better. It has not affected the way I am viewing football, but I admit I thought a lot about it."
One early test of his management came with the arrival of France goalkeeper Hugo Lloris, who was forced to watch from the bench in the early weeks of the season because of the fine form of Brad Friedel.
Lloris has since established himself as the No 1 at White Hart lane, but Villas-Boas admits it was a delicate balancing act.
"The arrival of Hugo Lloris? It was a difficult situation. We didn't want to be unfair. The ones who play have to deserve it with their performances.
"When Hugo was transferred it was to embody the Tottenham's future. His qualities have never been questioned, but Brad was very good at that moment. Hugo was transferred on Friday. The next day, Brad achieved an amazing match against Norwich.
"It was fair to play a boy with such performances level. That didn't mean I doubt about Hugo's qualities, but I wanted him to stand out on merit but not on his reputation. Sometimes you have to act considering the group not individual. It was difficult for Hugo.I admit sometimes it could make him impatient."
