Jurgen Klopp insists that he may keep changing Liverpool's formation despite Mohamed Salah's claim that he finds it "easier" in their well-established 4-3-3 setup.
Liverpool reverted to that system for Tuesday's Champions League clash at home to Napoli, having previously experimented with a couple of variations of a 4-4-2 - one that at times placed four players in attack, and one that included a midfield diamond.
Prior to that Klopp had almost exclusively stuck to the 4-3-3 system throughout his time on Merseyside, but after a poor start to this season he said that he needed to "reinvent" his side in wake of a 4-1 Champions League defeat to Napoli in September.
