Tottenham boss, Andre Villas-Boas, says he has learned from the mistakes of his short-lived spell at Chelsea and believes it has made him a better manager.
The Portuguese coach arrived at Stamford Bridge in the summer of 2011, following a record-breaking season with Porto that saw them surprise fans placing a bet on football, by doing the domestic double and winning the Europa League.
Part of his remit was to reinvigorate the squad as the Blues looked to be coming to end of a cycle, having relied on many of the players that saw them to success under Jose Mourinho for almost a decade.
However, the 35-year-old struggled to impose himself in West London, regularly clashing with some of the club’s senior squad members, as he immediately tried to change the playing staff, often excluding the likes of Frank Lampard and Ashley Cole form his starting line-up.
This inevitably led to tension at the club and he eventually left the Bridge in March, but was quickly brought back to the Premier League by local rivals, Tottenham, during the summer.
Despite losing both Luka Modric and Rafael van der Vaart in the summer, the young coach recruited extremely well and his side have now even set a target of finishing second in the table.
Villas-Boas freely admits that he made mistakes during his time at Chelsea but believes it has only benefited him at White Hart Lane.
"What we are doing nowadays at Tottenham with my staff is a reaction toward Chelsea, an echo to the mistakes we did," he told the Premier League betting news.
"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."
