Chelsea defender Cesar Azpilicueta admits team spirit has been knocked after recent results.
Defeat at Crystal Palace was followed by a draw with Champions League opponents Roma last night.
"The mood at the moment is not the best," Azpilicueta told the London Evening Standard.
"To come back into the game to get a point is big for the team, to show the character and that we won't give up.
"But the reality is that we have gone three games without a win and we will try to get back to winning ways on Saturday.
"It's true that we are not in our best moment. We came into the game after two consecutive defeats in the Premier League.
"We had the game in our hands when we were 2-0 up, but we also had it lost when we were 3-2 down. We managed to get a point, we are top of the group and we will keep fighting."
