Liverpool's players have returned to pre-season training - and that means the dreaded lactate test.
With the full squad back in action this week, the players were filmed taking part in the pre-season exercise that has typically been dominated by James Milner, who left the club on a free transfer this summer.
The 37-year-old, who ended his eight-year stay at Anfield earlier this summer as he departed the club to join Brighton and Hove Albion on a free transfer, had reigned as the Reds' fitness drills, and specifically the lactate acid test, champion in all of his eight pre-seasons with the club.
