Jurgen Klopp put his Liverpool players through a game of headers and volleys over a volleyball net on Wednesday as preparations continued for their trip to Chelsea.
In a big early test of their Premier League title, Klopp & Co. travel to Stamford Bridge on Sunday to face a Blues team tipped to push them all the way this season.
Liverpool were less than impressive at the back as they entertained newly promoted Leeds in their opening game, eventually winning 4-3 thanks to a Mohamed Salah penalty.
Chelsea were also not at their best in their first run out of the campaign but beat Brighton 3-1 to move above the champions in the early standings.
Ahead of the weekend, Klopp and his coaching team instructed Liverpool to header and volley the ball over the net in games of three vs three.
Summer signing Kostas Tsimikas was also on show, leaving Klopp with a fully fit squad to pick from apart from Alex Oxlade-Chamberlain.
