The new expanded FIFA Club World Cup will take place in the United States between 15 June to 13 July 2025.

Previously an annual tournament contested by the top seven teams, the Club World Cup will now feature 32 teams and occur once every four years.

The tournament once branded a “mistake” by ex-Fifa president Sepp Blatter is undergoing a revamp as significant as it is controversial.

How have teams qualified?

Teams from each of the six international football confederations will be at the Club World Cup: Asia (Afc), Africa (Caf), North and Central America (Concacaf), South America (Conmebol), Oceania (Ofc), and Europe (Uefa).

There are twelve places available for European clubs - the highest quota of the confederations. These places are decided by clubs’ Champions League performances over the last four seasons.

That means recent winners Chelsea, Manchester City and Real Madrid have all qualified.

Other European teams have qualified through a UEFA ranking system determined by clubs’ performances over the four seasons. Only two clubs per country can qualify, meaning 2022 Champions League finalists Liverpool are not included.

There are four club places each for Asia, Africa and also the North America and Central America federation.

Six places are awarded to South American clubs, and one to Oceania.

Clubs have accrued points over the most recent four seasons, based on their performances in their continental club competitions.

All qualifying teams have now been confirmed, the last being Botafogo, who beat Atletico Mineiro in the final of the South American Copa Libertadores.

Which clubs are taking part and who is seeded?

Pot 1: Manchester City, Real Madrid, Bayern Munich, Paris St-Germain, Flamengo, Palmeiras, River Plate, Fluminense

Pot 2: Chelsea, Borussia Dortmund, Inter Milan, Porto, Atletico Madrid, Benfica, Juventus, Salzburg

Pot 3: Al Hilal, Ulsan, Al Ahly, Wydad, Monterrey, Club Leon, Boca Juniors, Botafogo

Pot 4: Urawa Red Diamonds, Al Ain, Esperance Sportive de Tunisie, Mamelodi Sundowns, Pachuca, Seattle Sounders, Auckland City, Inter Miami

Why is Lionel Messi involved?

One spot in the tournament is reserved for a team from the host nation.

Fifa opted to awarded that place to Inter Miami for winning the 2024 MLS Supporters’ Shield, the trophy given out to the team which has the best regular season record. The Floridians then lost in the MLS play-offs, meaning they are not this season’s champions.

The invitation handed out to Lionel Messi’s Inter Miami has drawn some cynicism

The decision to invite Inter Miami to the Club World Cup before the MLS campaign was concluded has been interpreted by some as an attempt on Fifa’s part to ensure that Lionel Messi, who joined the team in 2023, will play in a tournament that has drawn little public enthusiasm so far.

When is the draw?

The draw for the revamped Club World Cup will take place at 18:00 GMT on Thursday 5 December.

You can follow the draw through live text on the BBC Sport website and app.

How does the format work?

The revamped Club World Cup will run in a similar way to the international men’s and women’s World Cup competitions.

The 32 teams will be divided into eight groups of four, who will play each other in a single round-robin format. The top two teams from each group will then go through to the knockout stages.

Unlike the international World Cups, the Club World Cup will have no third-place play-off.

The final will take place on 13 July 2025.

Where will matches be held?

All matches will be held in the United States, ahead of the country's co-hosting of the 2026 World Cup alongside Canada and Mexico.

Fixtures are set to be played in twelve different stadiums. The host venues are:

• Atlanta, Mercedes-Benz Stadium
• Charlotte, TQL Stadium
• Cincinnati, Bank of America Stadium
• Los Angeles, Rose Bowl Stadium
• Miami, Hard Rock Stadium
• Nashville, GEODIS Park
• New Jersey, MetLife Stadium
• Orlando, Camping World Stadium
• Orlando, Inter&Co Stadium
• Philadelphia, Lincoln Financial Field
• Seattle, Lumen Field
• Washington DC, Audi Field

The opening match will be held in Miami, and the final is scheduled for New Jersey.

Why is the new Club World Cup controversial?

Fifa is currently facing legal action, external from player unions and leagues about the scheduling of the tournament.

Global players’ union Fifpro and the top European Leagues say the international football calendar is “oversaturated” to the extent that it “risks player safety and wellbeing.”

Several players - including Liverpool's Alisson Becker and Manchester City's Rodri - have raised concerns about players’ wellbeing amid an increasingly jam-packed football calendar.

There are just five weeks between the Club World Cup final and the first Premier League match of the 2025-2026 season, which is scheduled for 16 August.

Manchester City manager Pep Guardiola has already requested a late start to the Premier League season for his team, while City midfielder Kevin De Bruyne told reporters: “The issue is that UEFA and Fifa keep adding extra matches, and we can raise concerns, but no solutions have been found. It seems that money speaks louder than the players’ voices."

A Fifa spokesperson BBC Sport: “The FIFA Club World Cup is not responsible for calendar congestion. It is a competitive tournament that takes place once every four years and, as independent studies have verified, FIFA is only responsible for a small percentage of matches per season.

“FIFA cares about the welfare of the players. Following a decision taken earlier this year, FIFA is formalising the Task Force on Player Welfare, headed by Arsène Wenger, to promote further global dialogue on player welfare issues with key stakeholders across football.”
