The World Cup winning former Brazilian boss was sacked by Blues owner Roman Abramovich after just seven months in charge in February 2009 following a disastrous run of results that threatened to ruin Chelsea's season before Guss Hiddink stepped in and guided the club to winning the FA Cup.
Scolari, now back in his native Brazil coaching Corinthians, conceded he had lost the dressing room and had targeted Adriano, the former Inter Milan star, to revive his side.

The 62-year-old pleaded with the Blues board to sanction the transfer with Drogba the makeweight in the deal only to see his hopes dashed just as they had been when he failed to sign Robinho from Real Madrid earlier in the season.
Scolari, who won just 20 of the 36 games he took charge at Chelsea, said: 'It was my fault that I could not control the locker room in different situations.
'I tried to do something about that and I tried to sign Robinho [who signed for Manchester City instead], because I wanted someone who could improvise. In England, you need someone like that.
'I also tried a switch to release Drogba for Adriano, because Adrianowas having some problems at Inter. I told the directors that I could manage his behaviour problems.'
Sad times: Scolari admits his failure at Stamford Bridge still upsets him, two years on from his sacking in 2009
Scolari admitted he lost the dressing room at Stamford Bridge and upset Drogba when he rejected the Ivory Coast international's request to embark on his rehabilitation from injury outside the club in France.
'He [Drogba] wanted to recover from injury in a big clinic in Paris, in the summer, I said no,' he said.
Scolari says he is still deeply regrets his overwhelming failure at Chelsea.
He added: 'Until this day, I'm saddened by what happened.
'It is a marvellous league, a dream place, my son was studying in a great school, we were living very well. That got me really sad.'
