The enduring rivalry between Internazionale and A.C. Milan has fostered what is one of the most prestigious, glamorous crosstown derbies in world football: the Derby della Madonnina.
The two genuine powerhouses of the Italian game have won 18 Scudetti apiece and 10 European Cups/Champions league titles between them.
Here we take a look at five of the most memorable clashes between the red and the blue sides of Milan.
They knew how to score goals back in the day.
Following up a 4-4 draw in February was always going to be tough, but the two Milan clubs went three goals better when they met again in November of 1949.
With the legendary Gre-No-Li triumvirate of Gunnar Gren, Gunnar Nordahl and Nils Liedholm in attack, Milan were a fearsome prospect.
The Rossoneri scored after just 36 seconds through Enrico Candiani, and then the winger put them two up in the seventh minute, grabbing an early brace.
Hungarian goal machine Istvan Nyers got Inter off the mark, but Milan pulled away again through Nordahl, and Liedholm made it 4-1 before the 20-minute mark.
Incredibly, the Nerrazurri would come back to take a 5-4 lead before Milan tied it up with 31 minutes left.
The players were presumably running out of steam by that point, and there was only one more goal in the match. It was netted by Amedeo Amadei, who completed his hat-trick and clinched a truly remarkable win for the Nerazzurri.
If you think the likes of Mario Balotelli and Antonio Cassano are very naughty boys, you might want to take a look at some of the hijinks players got up to back in the '60s to put things in perspective.
The first Derby della Madonnina of 1964 began well for Milan.
Giuliano Fortunato cut inside to his right and smacked home the opener for the Diavoli, though Inter fans claimed he was offside.
Milan legend Gianni Rivera scored the second goal to secure the result, but there was still plenty of action to come in the second half, most of it of the ultra-violent variety.
Inter's Spanish international, Luis Suarez, foreshadowed his trouble-making 21st-century namesake by smashing into defender Mario Trebbi and earning himself a red card.
From there, the match turned into a bloodbath, with Milan players copping the brunt of the punishment.
And to think, these two teams were at the pinnacle of European football at the time, having won the last two editions of the European Cup between them.
A much better version of the mythical Grande Inter side of the mid-1960s was on display a year later when, led by Sandro Mazzola, they ripped apart their archrivals.
Highlights of the 5-2 hammering included winger Mario Corso's rasping effort from the edge of the area, and Mazzola's jinking run and finish to complete the first of his two goals.
The result confirmed La Baneamata's status as the dominant force in the fashion city at the time.
Milan would not claim a win in any of the next seven derbies.
Milan were enduring the lowest period in their history, and a horror derby run, when they confronted the Nerazzurri in October of 1984.
In the 1980-81 season they had been demoted to Serie B for their part in a match-fixing scandal.
Though they gained promotion a year later, they were ill-equipped for Serie A and were relegated back to the second division again in 1982-83.
Facing up to derby No. 106, they had not experienced victory against Inter for six years.
When the team in black and blue scored first, thanks to a diving header from Alessandro Altobelli, it looked as though Milan's dark night of the soul was set to continue.
The Rossoneri showed tremendous resolve to scramble their way back into the contest, though, scoring an equalizer through Agostino Di Bartolomei after Ray Wilkins had set him up with a header across goal.
Milan kept applying pressure, and it was Englishman Mark Hateley who powered a header past Walter Zenga in the Inter goal to end his side's terrible run with utmost authority.
As the first derby match since the infamous abandoned Champions League quarter-final between the two Milan clubs, tensions were running at an all-time high coming into this clash.
Inter were the team with the most to prove, having not defeated their fierce rivals in their previous 10 attempts.
Adriano and Andriy Shevchenko exchanged penalties to send the teams in level at half-time.
In the second half, Dida palmed away a vicious Adriano free kick, but Obefami Martins was on hand to poke the rebound into the net and put Inter into the lead.
Giant Dutchman Jaap Staam soared highest to head home an Andrea Pirlo free kick and level the scores again.
Brazilian beefcake Adriano would have the final word, however, as he somehow managed to steer home a header under intense pressure two minutes into injury time, to give the derby a classic finish.
