Liverpool players were put through their paces in training ahead of the new season after being forced into a 'lactic acid' test - and not-so-surprisingly, Dominic Solanke and James Milner came out on top.
Pre-season must be the worst time for a footballer. After weeks of holidaying, late nights and alcohol, teams go through two months of intense fitness training and tests to make sure they're ready for the coming season.
One such test that took place at Melwood training ground was the lactic acid test; defined by Give Me Sport as:
"A test that measures the amount of lactic acid in your blood. This acid is made in muscle cells and red blood cells. It forms when your body turns food into energy.”
The premise of the test was to get players to run around a pitch within a certain amount of time in intervals - taking two minute breaks whilst blood tests were taken from their ears to measure the amount of lactic acid build up.
Players such as Roberto Firmino, Jordan Henderson and Joel Matip all took part - but the final two men left standing at the end were no other than English duo Dominic Solanke and James Milner.
Solanke, a summer signing by Jurgen Klopp, is fresh off the back of the U20's World Cup, where England won their first trophy since 1966, so he will understandably still be quite fresh.
However, despite being 31-years-old, Milner surprised no one with his fitness levels and finished top of the class. Known as one of the most professional players knocking around, Milner has never touched an alcoholic drink in his life, and was probably working hard over the summer to make sure he could hit the ground running for pre-season.
