So he hasn't yet scored 20 goals in a league season in his entire career and mostly in a two strikers formation.
I'm not sure if it can prove he is better than Osimhen for Barca (even if he is slightly more technical).
Barca always have bigger pull than Liverpool ever. Even before Barca first ever UCL. Pele had good history with Barca despite never joined. Johan, Maradona all were Barca players while they were still in their prime/young. That's 3 of GOAT footballers.
Maobappe joined super team that just won UCL and league and immediately they went trophyless meanwhile Qsg suddenly won the treble. Freaking Dembele has a better club season than any of Maobappe.
