This means that if players don't have enough fodder, finishing it won't be too costly. The requirements that must be followed to complete the challenge are listed below.FIFA 23 World Cup Challenge Japan SBC requirementsNumber of players in the squad: 11First Owned Players in the squad: Minimum of 1Number of players from Japan in the squad: Minimum of 1Clubs required in the squad: Minimum of 3Rare cards in the squad: Minimum of 1Player Card Quality in the squad: Minimum SilverChemistry Points required: Minimum of 14Rewards: 1x Gold Pack (Tradeable)Estimated Cost: 3,500 - 7,000 FUT coins across all platformsSBC cost analysisWhile more complex SBCs yield higher rewards, the single-task challenge is quite inexpensive and allows players to potentially get some valuable rewards that can be quite useful for their FIFA 23 squads.The cost of building a whole squad from scratch is somewhere around 5,000 FUT coins as per the current transfer market rates. However, one player on the team has to be 'first owned', meaning that the card may not be bought from the transfer market. Considering the humble requirements, using more fodder is also quite easy and, therefore, will bring the cost down further.There are no squad rating restrictions, and the fact that silver cards may be used to complete the squad means that FIFA 23 players can use a wide variety of undesirable cards. Picking up items from the market to fill gaps will also be quite cheap, and using a first-owned rare card will bring down the SBC cost further.EA SPORTS FIFA@EASPORTSFIFAAs the Knockout Stages approach, it's time to celebrate the players who have written past and present FIFA World Cup headlines for their countries FIFA World Cup Stories have landed in #FIFA23.
