"We aren't playing well as a back four and I'm not playing well personally. I need to hit better form and hopefully that will come in the next few games," said Carra.
"Over the last five or six years we have been renowned as a team who have kept a lot of clean sheets and for keeping it tight. I think that's why we get a bit more criticism because people don't expect it of Liverpool - and rightly so.
"We take the plaudits when things are going well so you have to take the criticism when it's not going well.
"I know I need to improve myself and we also need to improve as a team."
