Jamie Carragher says he and Javier Mascherano were to blame for Liverpool's defeat at Chelsea on Sunday.
Chelsea struck twice after Liverpool turned over possession and Carra said: "Games against Chelsea are notoriously tight and a bit of quality or a mistake is always going to be the thing that turns it one way or another.
"But we have lost the ball in midfield for their first and I felt myself that I should have done a bit better for their second one.
"I thought we played quite well and did all right for most of the game, yet we have still come away with a 2-0 defeat. It's the small details that are so important at this level and we know that there are certain areas we have got to improve. There's a gap at the top and we've got to close it."
