Jose Mourinho is eager to win the Champions League for a third time and insists playing on the European stage is vital for his developing Chelsea team.
Six years to the day since last taking charge of Chelsea in the Champions League, Mourinho's side on Wednesday night host Basle in Group E.
The Portuguese departed following a draw with Norway's Rosenberg on September 18, 2007, which extended Chelsea's winless run to three games, having twice reached the semi-finals of the Champions League, without going further.
Mourinho won the 2004 Champions League with Porto and 2010 competition with Inter Milan and Chelsea finally got their hands of the trophy they coveted most in 2012.
"I never felt the business was unfinished," said Mourinho, who believes he contributed to the Munich success.
"For me the important thing is that Chelsea had a dream and the dream became true, by winning the Champions League.
"When you work in a club and you work in that, you prepare the future, you leave something in the club that remains for years.
"Your business doesn't finish the day you leave, your business finishes the day everything you did disappears.
"It's normal that if you win it once you dream to win it twice. That happened to me.
"And when I won the second time I dreamed to win for a third time. That's the nature of football."
Chelsea last year became the first holders to suffer the ignominy of group stage elimination and they must end a three-match winless run to make a positive start to the campaign.
"I want to try to start the group phase by winning," he said.
"Last season Chelsea went outside his natural habitat, which is the Champions League. We don't want to do that again.
"It's important for a team of kids. It's very, very important for them to play on the big stage and the big stage is the Champions League."
Mourinho appears to be tempering expectations six years on from the end to his first spell as boss, by speaking of the need to nurture young talent.
Ahead of the Rosenberg clash, Mourinho delivered a cryptic message about eggs - interpreted as a parting shot at Roman Abramovich and the owner's recruitment policy.
Asked what his eggs are like now, Mourinho said: "Beautiful young eggs, eggs that need a mum, in this case a dad, to take care of them.
"And one day we'll arrive in a moment when the weather changes, the sun rises, we break the eggs and the eggs are ready to go for life at the top level."
Basle boss Murat Yakin says his side are underdogs, despite having a good record against English clubs, helping to knock out Manchester United from the 2011/12 Champions League and eliminating Tottenham from the Europa League last term.
"Chelsea is the clear favourite," Yakin said.
"We've got Schalke and (Steaua) Bucharest in this group. We'll be playing for second place with these two teams."
