#1 Roberto Firmino

Without a hint of doubt, Firmino is the jewel in Klopp's crown at Liverpool.
His importance to the team is often overlooked because of the performance of Coutinho, Salah or Mane but if Firmino ticks, the whole team ticks.
The Brazilian is a menace for the defenders as he moves around the pitch, dragging players out of position by dropping deep to receive the ball. This often creates space for the likes of Salah or Mane to run into and wreak havoc.
No player in the current Liverpool side has been involved in more goals than FIrmino since Klopp took over as manager. Nevertheless, he is often criticised for not scoring enough despite playing as the striker up front but that argument should be put to rest for now.
Firmino has scored 16 goals and provided 8 assists this season in all competitions which is more than the direct goal contribution of the likes of Romelu Lukaku, Sergio Aguero, Alvaro Morata or Alexandre Lacazette.
His tenacity often helps Liverpool win the ball high up the pitch and create a goal scoring chance out of nothing.
