"he plays up front as part of a fluid three"? Wow.
But no. He plays as our main, central striker. A number 9.
And he's not very good at it, because he isn't a a very good finisher and he's slow.
As for the Kuyt comparisons, unsurprisingly you're wrong again, but even if one were to examine Kuyt's usual output - often delivering 14-15 goals a season (more than Firmino has ever managed for Liverpool) plus Kuyt often delivered that impressive goal tally from a position playing on the right wing.
Firmino scored 10 league goals in his first season and 11 in his last. That last season saw him outscored by 17 other players in the Premier league, including Benteke, Olivier Giroud, Josh King and Son Heung-min.
And before you start quacking on about his fucking assists, it's GOALS that count for a striker, but even so, players like Delle Ali, Sanchez, Cost and Kane all managed to score twice as many goals and deliver the same - or more - number of assists.
Because Firmino isn't very good.
