A banner hung from San Siro’s Curva Sud before kickoff claimed that every devil in hell had come to support Milan but they forgot the one who lives in the details. You can make a stadium into an inferno for an evening but leaving Edin Dzeko marked by a full-back at a corner is a recipe for eternal regret.

“He’s a lot bigger than me, there’s not much to be done,” said Davide Calabria of the goal that set Inter on the way to a 2-0 victory over the Rossoneri in the first leg of their Champions League semi-final. The biggest Milan derby in two decades was barely eight minutes old when Dzeko hooked his leg around the defender and volleyed home.

It was, according to La Gazzetta dello Sport, the first time Stefano Pioli’s team had conceded from a corner in 104 attempts, yet it felt all too familiar. Inter won their previous match against Milan, three months ago, with a goal from the same source: Hakan Calhanoglu delivering both crosses from the same corner of the same ground these teams share. The only difference was the scorer: Dzeko this time, Lautaro Martínez back then.
