The self-styled 'Special One' left his role as Blues
boss in September 2007, just over three years after he started his
trophy-laden spell in charge.
Under the Portuguese coach, Chelsea twice made it to the
Champions League semi-finals, where they lost both times to
Liverpool.
Last season, months after Mourinho left and with Avram Grant at
the helm, the Londoners went a step further but saw their hopes
ended with a penalty shootout defeat to Manchester United in the
final.
The former Porto coach, who is now in charge at Inter Milan, is
in no doubt that had he remained as Blues boss, Champions League
glory would have been delivered.
"While I was at Chelsea we did everything but win the Champions
League. We won all the other big, big trophies. There was the first
league title for Chelsea in 50 years and the next year we were
champions again," he told the News of the World.
"We won the first FA Cup at the new Wembley, beating Sir Alex
Ferguson
and Manchester United. And two Carling Cups.
"So we'd won absolutely everything apart from the Champions
League. But people always want more - and at Chelsea that was the
Champions League. I would have won it with Chelsea.
"My contract was until 2011, so I would have been there for
seven years. It's enough time."
