Jose Mourinho says he "cannot promise" a spot in the Champions League next season for Chelsea.
Chelsea currently sit 15th in the table after winning just three matches.
"Chelsea is a big club. It's the club that I choose to come to. It's a club I live in a very specific way every day.
"Liverpool is a big club, Manchester United is a super big club. Last season Liverpool win nothing and didn't qualify for the Champions League.
"Two years ago Man United didn't qualify for the Champions League - not even Europa League - and won nothing.
"They are still a monster club, but that's football."
The job status of Mourinho is in doubt.
Asked if he had been given a guarantee about his job status, Mourinho replied: "I don't have to tell you."
