Well I don't think Laca is a clear 9 when Auba is on the wing. They switch and Laca is coming to defend etc.
I cannot upload a picture here, wtf. And understat.com doesn't allow to copy paste link to the picture. Anyway, you can find it here: https://understat.com/player/3277, and put Firmino to comparison, and choose season 2018/2019.
Laca first, Firmino in brackets:
xGChain90 0.80 (vs 0.83)
xGBuildup90 0.32 (vs 0.31)
G90 0.47 (vs 0.41)
xG90 0.43 (vs 0.47)
Sh90 2.92 (vs 2.57)
A90 0.29 (vs 0.21)
xA90 0.15 (vs 0.22)
KP 90 1.12 (vs 1.47)
What do you base on the "falls well short of Firmino creatively"? That sounds like a very big difference.
Take into account the quality difference in one winger and at least one fullback between the teams last season (Jenkinson/Lichtsteiner + Iwobi/Mkhi). Them making mistakes naturally affects Laca's stats.
I mean Lacazette’s natural position both at Arsenal and before where’s Firmino has never really specialised in leading the line.
He’s always been more of a second striker, tbf those numbers are pretty similar but in terms of the eye test I’ve seen Firmino make dribbles and passes that I’ve never seen Lacazette make.
