We lost the league because of all the points we lost throughout the season, not just against Bologna. At the end of season the team that fuck up less win the league and it was Milan. They took advantage of their opportunities the most and won it.
We can blame Radu for his fuck up against Bologna, we can blame Dimarco for his penalty miss against Atalanta, we can blame Lautaro for his penalty miss against Milan, we can blame Handa, De Vrij and Sanchez for the goals we conceded against Milan, but none of them alone cost us the league.
Anyway, no point to linger on regrets. Let's move on.
