Despite concerns over ticket sales and player fatigue, Fifa's new expanded Club World Cup will throw up several intriguing storylines this summer in the United States. Catch all the action live on SuperSport.
AFP Sport picks five things to look out for on the pitch as teams compete to conquer the world and claim their share of $1 billion in prize money.
MESSI BACK IN THE SPOTLIGHT
Former Barcelona great Lionel Messi has spent the last two seasons at MLS side Inter Miami but the Club World Cup pits him against European opposition once again.
The 37-year-old superstar still possesses supreme quality but there are question marks over whether he and former top level stars Luis Suarez, Jordi Alba and Sergio Busquets can seriously compete against the cream of the crop.
Inter Miami face Porto in their second group match in Atlanta, a team Messi has faced once before, beating them with Barca in the Uefa Super Cup back in 2011.
Messi also featured against Porto in a friendly with Barca back in 2003, which was his first ever appearance for the club at 16 years old.
If he nets at the tournament, Messi would become the oldest ever Club World Cup goalscorer, while both he and Suarez trail the competition's all-time top scorer, Cristiano Ronaldo, by two goals.
A NEW STAGE FOR DOUE
Paris Saint-Germain's Champions League final romp over Inter Milan was inspired by thrilling forward Desire Doue, who turned 20 earlier in June.
His spectacular burst into the limelight over the past few months means he is one of the players to watch this summer at the Club World Cup.
He struck twice in the final against Inter as well as setting up another goal and drew comparisons to Spanish starlet Lamine Yamal, who will not be playing this summer as Barcelona did not qualify.
PSG's opening clash against Atletico Madrid at the Rose Bowl in Los Angeles immediately gives Doue another stage to shine on as the world at large continues to discover his immense talent.
REVAMPED CITY
Pep Guardiola's Manchester City endured a poor season by their lofty standards and immediately took action in the special transfer window to bolster their squad for the Club World Cup.
The Abu Dhabi-owned club have already splashed more than £100 million ($136 million) on Tijjani Reijnders, Rayan Ait-Nouri and Rayan Cherki.
With holding midfielder Rodri also returning to fitness after injury, City are hoping they can step up their game significantly.
French 21-year-old attacking midfielder Cherki is an exciting talent looking to show his quality at the top level.
"I really believe he can become a world-class player with our support and direction," said City's director of football Hugo Viana.
SOUTH AMERICAN THREAT
While Europe's elite are at the end of a long, hard season, South American clubs are midway through their campaigns and will be energised.
They have long revered the competition to a far greater degree than European sides, as it represents the chance to face the very best teams in the world.
Fans who do not regularly follow South American football can look forward to discovering some of the most exciting emerging talents in the world.
River Plate's Argentine playmaker Franco Mastantuono will join Real Madrid after the tournament, while Chelsea-bound striker Estevao Willian is hoping to end his time at Brazilian side Palmeiras with a bang.
ATLETICO HUNGER
Atletico Madrid ended the season trophyless despite looking like potential contenders in Spain and Europe.
Diego Simeone's side are proud of having reached the tournament ahead of LaLiga rivals Barcelona and the coach has not hidden his desire to succeed this summer.
"I hope we can advance in the Club World Cup and lead Atletico Madrid to a privileged position," said Simeone.
Atletico have not won a single trophy since lifting LaLiga in 2021 and their last success outside of Spanish football came in 2018 with Europa League and Uefa Super Cup wins.
Their elimination by Real Madrid in the Champions League after Julian Alvarez's controversial 'double-touch' penalty was disallowed sent them into a spiral, which they only managed to shake off in the final weeks of the season, after their chances of success had vanished.
