Chelsea are languishing 15th in the table with just 11 points from their first 10 games ahead of tomorrow's lunchtime showdown with Liverpool .
No team has made fourth place with less than 13 points at this stage of the season.
Chelsea have won just one of their last seven games in all competitions with Mourinho convinced they will eventually turn the corner.
But he stopped short of promising a top-four finish.
Mourinho said: “No (doubt we will get out of this). I cannot promise (we will qualify for the Champions League).”
And Mourinho warned being a big club doesn't guarantee a place in Europe's top club competition.
He said: “Chelsea is a big club. It's the club I chose to come to.
“A club I live in a very specific way, with respect. Liverpool is a big club.
“Man United is a super big club. Last season Liverpool won nothing and
didn't qualify for the Champions League, and they are still a big club.
“Two years ago United didn't qualify for the Champions League, not even the Europa League, won nothing, and they are still a monster club. That is football.”
