Jurgen Klopp has a special affinity for players who can dodge injury. And for a long time at Liverpool, Nathaniel Clyne was a player he held in particularly high regard.
'The manager has called me a machine in the past,' Clyne said in 2016. 'I'm not entirely sure why, it's probably because I play in loads of games and rarely get injured or come off with knocks.'
He was almost certainly correct. In the early stage of his Liverpool revolution, Klopp had to made hard calls on the players who did not have the physicality to enforce the high-octane pressing system he was to oversee.
