Chelsea winger Mykhaylo Mudryk says the players can feel the frustration of fans after defeat at home to Brighton.
The Blues have now lost four consecutive games.
"I think the first half was not so good. When in the second half we started to play, it was already late," said Mudryk, before adding, "For all of us it is a hard period but we never give up, we keep going and everything can change."
Mudryk also said: "We all feel it.
"We want to win but now it is hard for us but like I say, we keep training hard and one day everything can be changed."
He also said: "We are already thinking about the next game, the Champions League. It is a big opportunity for us and we should all show our best."
