During Inter's 1-0 over AC Milan, it became clear that we were watching two teams moving in opposite directions.
Yes, Milan had chances to equalize and wasn't really deserving of the zero points, but Inter's road win in this classic Derby served as a huge statement nonetheless.
Inter moved into fourth in Serie A while Milan's continued struggles dropped it all the way down to 11th, a painful 12 points behind Juventus already.
Let's take a look at what else we learned on Sunday.
Milan Still Can't Stop Free Kicks
Another game, another free-kick goal given up by AC Milan.
Granted, Antonio Cassano went down rather easily in the third minute to draw the soon-to-be soul-crusher for Inter, but the Red and Blacks need a find a way to defend the set pieces more effectively.
Esteban Cambiasso whipped in the ball to the far post where defender Walter Samuel, in the middle of a tussle with Matteo De Sciglio, managed to get his head to it for the opening goal. Just like that, it was 1-0.
It was already the seventh goal Milan has conceded via free kick this season, and although it should have been equalized later in the match—some missed chances were their fault, some were not—it can't keep getting burned via the set pieces.
Inter is Dangerous on the Road
I thought soccer was supposed to be a tough sport to play on the road.
Apparently not for Inter.
The Black and Blues are 5-0-2 this season in Serie A, but just one of those wins and both losses have come at San Siro. That means they are 4-0-0 so far this season away from home, which is an incredible feat.
Not only that, but Inter has outscored opponents 8-0 on the road and hasn't conceded in nearly 600 minutes.
Of course, this one was "on the road," but not technically "on the road." Still, when you can dominate matches like that away from home, it's going to be a lot easier to have league success. Inter is finding that out now, as it currently sits just four points behind first-place Juventus and Napoli.
The Milan Derby is as Thrilling as Ever
Serie A has lost lots of talent over the past years, but the Milan Derby, as evidenced on Sunday afternoon, is just as thrilling as ever.
While the 1-0 final certainly could have—and should have—had more goals, it wasn't lacking drama.
Inter was given a red card in the first half, the fans were loud, the opportunities were constant and most importantly for a good rivalry, the players were clearly ready to impose some violence on each other.
The matchup that has been called "Il Crashico" in the past was far from disappointing.
