we have won the Coppa 9 times in a 100 years history before Max. with him, we have 4 in 4 years.
but the thing is, teams didnt give as much a shit about it in the past as they do now. top clubs understandably prioritized national leagues and european cups over them, which is why you have Barcelona and Bilbao having more Copa del Reys than Real (they didnt win in 20-30 years before Mourinho took over i think, going out vs 3rd tier clubs regularly). it is why we were tied with Roma at 9, while having 29 more scudetti, before Max joined. and why Arsenal has won it more times than Pool and United. it is only recently, when all these trebles, quadrouples and stuff like that became a trend, that teams try to win it every year.
