Jose Mourinho believes Chelsea can still win the quadruple despite their poor start to the season.
The Blues face Dynamo Kiev in the Champions League on Tuesday, with Mourinho refusing to prioritise the club's European pursuit over an ailing Premier League challenge.
“We can win all four [competitions], we can lose all four,” he said. “I think it is possible, but I think it’s also possible to lose all four.
"Everything is open. We are in October. For us, it depends on other teams, depends on other results. We don’t depend on ourselves, we depend on what happens also in other matches and other teams."
Although Chelsea are struggling in 12th in the Premier League after nine matches, Mourinho remains confident that the Blues will finish in the top four.
"My opinion is we are not going to miss out on the Champions League," he said.
