El Clasico, De Klassieker, Derby della Capitale! Are you ready for Sunday’s derby bonanza?
A quick look at Sunday’s fixtures will unveil a host of mouth-watering derby games. Planet Sport takes a look at the 15 matches in chronological order… in case you're crazy enough to watch them all!
Most of the noise this weekend will be around El Classico. That shouldn't come as a surprise - after all, it is one of the biggest sporting events on the planet.
However, there's a lot more derby action where that came from. In fact, it seems like league organisers from across the world were in cahoots, as some of the biggest rivalries in football have 'coincidentally' landed on the same day.
01:00 GMT: Tigres UANL vs Monterrey (Clasico Regiomontano)
Mexican football made worldwide headlines a fortnight ago as a number of fans - unconfirmed reports suggest the number is around 17 - lost their lives in a riot which took place during a top tier match between Queretaro and Atlas.
Tigres UANL and Monterrey are cross-town rivals and have been going head-to-head since 1973. Considering both teams have started the new season well, another intense encounter is expected.
12:00 GMT: AS Monaco vs Paris Saint-Germain
AS Monaco were promoted to Ligue 1 in 2013 and in their first season back, they finished second - nine points away from title winners PSG. For the next four years, the two clubs built a serious rivalry as they battled on the domestic and European fronts.
Following the departures of key players - including Kylian Mbappe who moved to PSG - Monaco lost momentum and since 2018 they have failed to reach those same heights.
Despite that, the south-coast side are rebuilding and this weekend's game will give us an indication to how close they truly are to the elite. Plus, with PSG enduring some tough moments lately, they will also be targeting a strong performance.
13:30 GMT: Ajax vs Feyenoord (De Klassieker)
The biggest game on the Dutch football calendar takes place this Sunday as Ajax welcome Feyenoord for the 199th edition of De Klassieker.
But if cultural differences weren't enough, there are also major title implications. A win for Ajax will keep them top of the table. However, should they lose, they could open the door for PSV in what is quickly becoming an enthralling race for the championship.
15:30 GMT: Grasshoppers vs FC Basel
16:00 GMT: Rapid Vienna vs Austria Vienna (Wiener derby)
The city of Vienna will be rocking this weekend as two of Austria's most successful clubs clash at the Allianz Stadion.
Rapid Vienna, who are largely supported by the working classes, and Austria Vienna, who are regarded as the team of the bourgeois, have won more silverware than any other club in the country.
What's more, they were the only two Austrian sides to have never suffered relegation - both competing in the top flight since 1911.
16:30 GMT: Tottenham vs West Ham (London derby)
We go from one city derby to another as Tottenham and West Ham battle over bragging rights in London.
West Ham experienced a great atmosphere last Thursday against Sevilla, and they can expect the same when they make thr short trip across to the Tottenham Hotspur Stadium.
17:00 GMT: AS Roma vs Lazio (Derby della Capitale)
The history of the Rome derby is particularly interesting. AS Roma were created as a result of a merger, instigated by the country's dictator Benito Mussolini who wanted one Roman club. Lazio were the only club to resist and the rivalry was born.
17:00 GMT: Rosario Central vs Newells Old Boys (Rosario derby)
17:30 GMT: AEK vs PAOK (Double-headed eagles derby)
This fixture never provided too much conflict in the stands - that is, until 2017. Since that year, both clubs have battled for silverware on numerous occasions and the hostilities have been on the rise.
19:00 GMT: Flamengo vs Vasco da Gama (Classico dos Milhoes)
The two Rio de Janeiro clubs are among the most supported in Brazil, which has led this fixture to be known as the Derby of Millions.
19:15 GMT: Gimnasia La Plata vs Estudiantes (La Plata derby)
The second of Argentina's triple-header comes from the city of La Plata.
19:45 GMT: Marseille vs Nice (Derby de la Mediterranee)
French police tend to identify this fixture as 'high-risk' and if you don't know why, let me remind you of what happened when Marseille and Nice met back in August.
Their Ligue 1 encounter was suspended and had to be replayed at a later date, following a mass brawl between players, staff and the supporters. The chaos ensued after Nice supporters pelted Marseille's Dimitri Payet with projectiles as he attempted to take a corner.
20:00 GMT: Real Madrid vs Barcelona (El Clasico)
Real Madrid are powering towards the La Liga title, and it would take an extraordinary turn of form in order to change that.
However, Barcelona can certainly sour their success with a derby win at Santiago Bernabeu. This may not be the Barca of old, but they have certainly improved under Xavi and could give Los Blancos a run for their money.
22:00 GMT: River Plate vs Boca Juniors (Superclasico)
Back in 2004, The Observer encapsulated this match, saying: "Derby day in Buenos Aires makes the Old Firm game look like a primary school kick-about."
