Liverpool delivered a statement win at Anfield on Wednesday night, defeating Leeds United by six goals to nil and closing the gap to Manchester City to just three points.
The Reds were largely flawless, and the strength of their performance was epitomised by Sadio Mane, who did exactly what was necessary to cause problems for Marcelo Bielsa's men.
Leeds have executed man-marking all over the pitch since Bielsa was appointed at Elland Road in 2018. It is a unique strategy and one that is quite rare at the top of the modern game.
