Jose Mourinho does not consider that he has unfinished business as Chelsea manager in the Champions League.

Six years to the day since last taking charge of Chelsea in the Champions League, Mourinho's side host on Wednesday night Basel in Group E.

The Portuguese departed following a draw with Norway's Rosenberg on September 18, 2007, and missed out on adding the European Cup to his CV.

Yet Mourinho feels he played a part in Chelsea's 2012 Munich success.

"I never felt the business was unfinished," said Mourinho, who won the 2004 Champions League with Porto and 2010 competition with Inter Milan.

"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 disappear."

Mourinho felt it was just that Chelsea won the trophy after Luis Garcia's ghost goal for Liverpool, some controversial encounters with Barcelona and a 2008 penalty shootout defeat to Manchester United.

"Some of the players were in every one of those moments," Mourinho added.

"When Chelsea won the Champions League the gods of football made justice with the club and with a group of players that did so much to touch that cup."

Mourinho sought to temper expectations on his young players by targeting merely progression to the knockout stages.

He plans to select four players aged 22 or under for the Blues' first return to the Champions League since last season suffering the ignominy of becoming the first holders to exit at the group stages.

Chelsea responded by winning the Europa League and beat Basel in the semi-finals.

The Swiss side gave Chelsea a fright, levelling the tie on aggregate at half-time of the second leg at Stamford Bridge, before a second-half surge which showed the Blues' capabilities.

Basel are wary of their opponents.

Defender Kay Voser said on "Chelsea has a tremendous quality and can shift up a gear when it needs to."

Since the May meeting Chelsea have been boosted by Mourinho's arrival and numerous summer signings.

Nevertheless, Basel boss Murat Yakin is optimistic in a group which also includes Steaua Bucharest and Schalke.

"We are targeting the second round," Yakin said.

"To qualify you need to finish in second place, and this is possible.

"It takes a Basel as last year, with fearless courage to play good football."
