The Blues have struggled domestically this season, with the Premier League title holders languishing 14 points off the pace in 15th position.
However, the Blues can can qualify for the knockout rounds of the Champions League with a match to spare if they overcome Maccabi Tel-Aviv and Dynamo Kiev fail to beat Porto on Tuesday.
Mourinho remains hopeful about Chelsea’s chances, pointing to his against-the-odds tournament triumphs with Porto and Inter.
“I know – and also Chelsea – we know that sometimes you win when you are not the favourites,” he told reporters.
“When I won it twice with Porto and Inter we were far from favourites. We were not even top 10 favourites.
