Chelsea striker Tammy Abraham was left frustrated after their 2-2 draw with Sheffield United.
Abraham struck twice for the draw.
"We are all disappointed with this draw," he said.
"We're Chelsea and no team should be able to come here and play better than us, and Sheffield United were better than us in the second half. It wasn't good enough from all of us. I take responsibility as well being one of the players out there.
"We were gifted two goals in the first half and from there we should have killed the game off, come out in the second half and upset the opposition. We know Sheffield United will always fight till the end.
"We should have frustrated them, but them scoring an early goal in the second half didn't help. From there we had to relax, calm everything down, and go out there and win the game.
"It just wasn't our day," added Abraham. "We have to go on the international break now and calm back down with all our heads focused and screwed on. We need to get these wins."
