Denis Zakaria has urged Chelsea teammates to maintain full focus against Leeds.
He admits there are no easy solutions when you are in a run as Chelsea is.
"It's a tough one for us," he said. "We're working hard, trying to change the situation and for the moment it hasn't worked on our side. We all want the best result, for sure, but for the minute it doesn't work. But I'm sure and I'm confident that it will change fast because we are doing everything to change that and I'm sure that it will change soon.
"When it is a tough moment, things are bad and you don't have the luck on your side, it is difficult to say what is the problem, but I think that we have to work.
"That's the point, we have to work to do better and we know that we have to do better for the next game because I know that we can do good things."
