Liverpool defender Martin Skrtel is delighted over his developing partnership with Dan Agger.
The pair have started the last six Barclays Premier League games alongside each other but the Slovakian is well aware of the quality ready to step in from the sidelines.
"Daniel is a top quality player and is easy to play alongside," Skrtel told Liverpoolfc.tv.
"We have a very good understanding on the pitch which is important and we are working hard and enjoying our job. I think we are doing well together.
"Our squad is now very strong. That is very important for the team because we have a lot of games in front of us, especially January when we have cup matches as well, so we need everybody fresh."
