Borussia Dortmund - German Bundesliga

Borussia Dortmund of the German Bundesliga plays its home games at the Westfalenstadion (pictured), known as Signal Iduna Park for sponsorship reasons. The 81,365-capacity stadium is the largest in Germany, and Borussia Dortmund sells every ticket whenever it plays at home. Dortmund's average attendance of 81,365 is the largest in world soccer.

Although Dortmund has won the Bundesliga title eight times, they have not lifted the famous trophy since the 2011-12 season. This is because Bayern Munich has historically dominated German soccer. While Dortmund is rarely the favorite with My Bookie’s mobile app to win the league title because of Munich's domination, they regularly go into games odds-on to win, especially at home.

According to Forbes, Dortmund is the 12th most valuable soccer team on the planet, with a valuation of $1.98 billion.

River Plate - Argentinian Primera Division

River Plate, or Club Atletico River Plate to give it its full title, is an Argentine professional sports club best known for its soccer team of the same name. River Plate plays home games at the Estadio Mas Monumental, an 84,567-capacity stadium. On average, 80,093 adoring fans pack into the ground for each home game, creating an unrivaled, hostile atmosphere.

With 38 Primera Division titles, River Plate is Argentina's most successful soccer team. Only Boca Juniors, with 35 league wins, is close to River Plate in terms of success. Unsurprisingly, River Plate and Boca Juniors share a fierce rivalry, with more than half of the country's soccer fans supporting these clubs. The Superclasico local derby between River Plate and Boca Juniors is one of the most famous derbies in the world, although attending the fixture is not for the fainthearted.

Bayern Munich - German Bundesliga

Bayern Munich's Allianz Arena has a 75,024 capacity, which it fills every home game; the German giants have an average attendance of 75,000. Munich is by far the most successful German soccer team with a record 33 Bundesliga titles, 20 DFB-Pokal cups, ten DFB/DFL-Supercup wins, and six DFL-Ligapokal wins. Bayern also excelled in European competition, having won the UEFA Champions League six times; only AC Milan (7) and Real Madrid (15) triumphed more.

It should not be surprising to discover Munich is one of the world's wealthiest soccer clubs. It has the largest revenue of any German sports club and is the third highest-earning soccer club in the world. In 2021, Munich earned €634.1 million ($667.8 million). Forbes values Bayern Munich at a cool $5 billion.

Manchester United - English Premier League

Manchester United is one of the most famous soccer clubs in the world, and it has a passionate, global fanbase. The English Premier League's Old Trafford home has a 74,310-seater capacity, and an average of 73,861 supporters turn out for each home fixture.

The club enjoyed much success in 1960, thanks partly to a first team featuring superstars like George Best, Bobby Charlton, and Dennis Law. Manchester United dominated English soccer throughout the 1990s and early 2000s. Under the guidance of iconic manager Sir Alex Ferguson, between 1992-93 and 2012-13, Manchester United won the Premier League title 13 times, including an incredible treble in 1998-99 when the team won the Premier League, FA Cup, and UEFA Champions League.

Although Manchester United has struggled in recent seasons, the club is still arguably the most famous on Earth. Forbes values the Old Trafford-based team at $6.55 billion, slightly less than the $6.6 billion valuation of Spanish giants Real Madrid.

Plans are afoot to expand Old Trafford with a new 100,000-seat stadium, which will cost approximately £2 billion ($2.5 billion). Should those plans come to fruition, the new Old Trafford will be one of only 12 sports stadiums to boast a six-figure capacity.

Inter Milan - Italian Serie A

Internazionale, widely known as Inter Milan or simply Inter, boasts the largest average attendance in Italy's Serie A. When non-Italian fans are asked to name an Italian team, they often cite Juventus or AC Milan, but Inter, with its 72,199 average attendance, has the most match-going fans.

Inter plays its home games at the world-famous Stadio Giuseppe Meazza, better known as the San Siro. The stadium has a maximum capacity of 80,018, but it is limited to 75,817 most of the time. Each Inter home game attracts an average of 72,199 fans. Inter shares the stadium with arch-rivals AC Milan. The two city rivals compete in the Derby della Madonnina, which sports writers often rank in the top ten sporting events you should witness live at least once in your life.

An interesting fact about Inter is that it is the only Italian club to have never been relegated from Serie A. It shared that impressive record with Juventus until 2006 when Italian soccer authorities relegated Juventus amidst the Italian match-fixing scandal.
