Klopp switched from his favourite 4-3-3 formation to a 4-4-2 to offer his oft-maligned defence balance and his attack, more potency on the counter.
And the 25-year-old, described by the gaffer as a 'real goal threat', did so fantastically, as his sixth and seventh league strikes helped the Reds to a comprehensive win over the Hammers at the London Stadium.
“He is a real goal threat,” Klopp said after the game.
“He’s an offensive midfield player who is more a striker, that’s true, and he needed to adapt a little bit to the different style.
“He played very often as a second striker at Roma with [Edin] Dzeko. Today he had the position, obviously he likes it. We will see what we make of it.”
