With Mohamed Salah regularly deployed as the most advanced forward for the Reds this season, Firmino has been used in a deeper position by the Reds boss.

He performed to devastating effect in the final game of 2018, scoring twice in 90 seconds to overturn an early concession and later sealing his hat-trick from the penalty spot.

Asked about the Brazilian following a result that moved Liverpool further clear at the Premier League summit, Klopp described the pivotal role Firmino plays for his team whether among the goals or not.
