Andre Villas-Boas has admitted managing Chelsea was “too much too soon” and blasted Spurs chairman as an “expert in sacking managers”.
The Portuguese manager was hailed as the successor to Jose Mourinho but lasted just over two years in English football.
Aged just 33 he became the youngest manager to win a European competition, guiding Porto to the Europa League title and adding the Portuguese league and cup to secure the treble in his first season.
His success alerted Chelsea and Villas-Boas, known to fans as AVB, took over at Stamford Bridge.
But AVB lasted just nine months in the job and he now believes he took the job too early in his managerial career.
Speaking at final day of the ASPIRE4SPORT and the Aspire Academy Global Summit on Football Performance & Science which is taking place at the iconic Amsterdam ArenA, home of AFC Ajax, he said: “The Chelsea experience was too much too soon.
“I wasn’t flexible as a manager at that time. I was communicative, but I wasn’t flexible in my approach. At Tottenham I learnt to be different.
“In professional football you have to live the day-to-day. The objective is the group performance, but every single individual requires a different response from a manager – you can’t be the same person to each player.
“At Chelsea the group was more important, I stuck to my methods too much.”
But, while pragmatic about the reason his Chelsea career faltered, Villas-Boas saved his harshest words for Daniel Levy.
AVB, now 38, added: “Daniel Levy is an expert in sacking managers. There’s no time for long term projects in the Premier League.”
Villas-Boas’s left his last coaching role – at Zenit St. Petersburg – at the end of last season.
