Ross Barkley admits there was great disappointment inside the Chelsea dressing room after Saturday's 2-2 draw with Sheffield United.
Tammy Abraham scored twice in the first 43 minutes, but Chelsea were pegged back in the second-half.
Barkley said: “There's loads of talent in there in the changing room. The players we've got are unbelievable but today we weren't at the level we should be. We didn't perform well.
“You've just got to try and make things happen and we didn't create enough chances, didn't hit the target as much as we should have.
“But we all know. We all spoke in the changing room after the game and we all held our hands up. Tammy scored two goals but he can't win the game on his own."
