David Luiz admits Chelsea's defence was at fault for defeat to Liverpool.

On the lack of marking by the team that allowed Jurgen Klopp's side to take the lead, Luiz says they should've been better organised.

"Normally you have a line to defend the free-kick but they played short and they played quickly, and we didn't organise the line quickly so that is why they had two or three free players at the back and they scored a goal. "This is the Premier League. When you make a mistake and don't pay attention, particularly from the free-kick, you pay."
