Chelsea manager Jose Mourinho is refusing to rule out the possibility that his side can no longer win the quadruple, despite the Blues suffering a horrendous start to their campaign.

Despite having lost four matches in the Premier League as well as their most recent Champions League fixture against Porto, the Chelsea boss remains confident that his team can still claim an unprecedented four trophies this season.

"We can win all four. Everything is open - we are only in October," Mourinho said ahead of Tuesday's meeting with Dynamo Kyiv.

"It is possible, to win all four trophies is something really amazingly difficult.

"The difference between challenging for the title and for the top four is not so big. I don't know if there is a margin for error. We go with everything all the way and let's see."
