Liverpool defender Ragnar Klavan says they're working to improve their set pieces in attack.

The Estonian centre-back, who joined the Reds in the summer from FC Augsburg, scored the first goal in a 3-0 win over Derby in the EFL Cup last night.

"We work a lot on defensive set-pieces and also offensive ones," he told Liverpool's official website.

"Slowly, you can see our defensive ones are getting better and also our offensive ones - we are nicking some goals.

"I was there and made a goal and after that we didn't give away any goals and, to the end, we were good."
