Dortmund fans waved their scarves and sang their chants.
Anyone who did not know better would have thought they were the ones who had scored.
The two teams from the Ruhr Area had some of the most passionate fanbases in the world.
Dortmund was luckier than Schalke 04 in that their executives were not complete idiots.
Schalke 04 had produced plenty of outstanding young players in recent years, but those players had not brought in much in transfer fees when they left.
Before long, they would be down in the second division singing "Unforgivable" alongside the King of the North, while their archrivals Dortmund remained in the Bundesliga to resist the Southern King and keep performing "One Step Away."
Play resumed, and the Professor lowered his head to fiddle with his tie.
The red-to-black gradient design was excellent, and the Saint George's Cross tie clip was equally exquisite.
It commemorated Saint George, the knight who stopped Rome's persecution of Christians. Legend had it that Saint George killed the dragon that had been forcing girls into sacrifice, and its blood flowed across the ground to form a cross.
Many club shirts and national flags were connected to Saint George's Cross.
The Professor could not help wondering whether Milan's shirts would one day feature something related to Saint Kevin.
Although Huang Kaiwen had not yet retired and had even spent four years away from Milan, his statistics, records, and influence had already far surpassed those of an ordinary player.
He was unquestionably Milan's greatest legend in over a hundred years.
Watching Huang Kaiwen's performance today, the Professor could hardly imagine how much the fans would miss him after he retired.
Even if a new king emerged, no one could replace a Huang Kaiwen like this.
