Tottenham boss Andre Villas-Boas is trying not to repeat the mistakes he made during his last management berth at Chelsea. The Portuguese tactician was appointed at Stamford Bridge in the summer of 2011 as the most highly-rated young coach in Europe, but lasted just nine months.
He told France Football: "What we are doing at Tottenham with my staff is a reaction to Chelsea, an echo to the mistakes we made.
"Not everything we did there was 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.
"I should have been given an opportunity to go on, but I am aware that, considering the results, change is the only way to make an impact.
"I would never have gone to Chelsea if I was not absolutely convinced that I could have been a success there."
