FIFA - Nephew sold player, now can't play anymore - help?

I think the support could give you a new one
heard from a friend that he sold a player on accident to cheap and EA refunded the player
but except that dunno dont play fifa sorry ;/

I highly doubt the game contains only one player for "that position". Sounds like fishy youthful trickery to me 😜 aka Daddy gimme money for shiny new players. But hey, maybe the kid made a mistake, and Fifa operates like this to draw more transactions.

Fifa games are a huuuge real money sink. If I were a father, I would limit my 9 year old to free-to-play modes, where no harm can be done.

You cant start over but even with microtransactions you absolutely don't need to pay real money if you even if accidentally sold player. You can buy cheap Gold players with coins you get for playing and still earn enough rewards to get better players. Its pretty easy to do, FIFA giving playing cards and packs with players every week for just playing game against AI or against real players. Also you can play Pro Clubs mode where you simply choose whatever team you like and playing, without picking players and buying them on transfer market.

I'm guessing this is about FUT (FIFA Ultimate Teams) .. well this is the mode that EA makes tons of money out of in FIFA games
I wonder if your nephew actually sold a OP expensive player for crazy cheap, or sold an average player for average price ?

I don't have a lot of experience with EA FIFA games (last one I played was FIFA 19 and not a lot of FUT), but I did a quick google and there seems to be something called "Quick Sell Recovery" EA help article for detailed info >> https://help.ea.com/en/help/fifa/learn-about-quick-sell-recovery-in-the-fifa-web-and-companion-apps/
However this seems to be for the latest FIFA game (which currently is FIFA 22), and you haven't mentioned which FIFA the problem is at .. so if it is in older fifa (fifa 21, fifa 20 or older for example) this recovery thing won't help .. it also work if that "Quick Sell" happened in no longer than 7 days ago
If that recovery didn't help then you may try contacting EA support and they "might" help
If your nephew sold an average player then he could use a substitute player of a different position temporarily till he earns enough coins to buy a new player suitable for the position

If this issue is indeed in FUT mode then tell his parents to watch out for their credit cards .. 9 years playing money sucking/gamble mode like FUT is a disaster waiting to explode soon.

Just play Efootball 2022 it's a FREE videogame,and you can get this occasion also for learn to your child to avoid to buy\play games from publishers that use microtransactions\fifapoints etc.

Euuhrm i would just start with the source, asking EA?

another easy solution would be that he can just sell another of his players and with the money he gets for that one he just buys two cheaper players again so he has a full roster :)

Reading through this whole thread I must say that I'm quite shocked of just how much football games seem to have changed, back when I used to play them with friends (about ten years ago) it was a lot simpler. Leave it to EA to turn something straightforward into a micro transaction minefield.
Guess I'll stick to Rocket League for the foreseeable future, it's a bit of a grind fest for cosmetics but at least they haven't messed with the actual gameplay so far.

Hey, I play ultimate team pretty often (which is the game mode he is probably talking about) and I think he is lying about not being able to play the game.
On Ultimate Team, you start with a roster of a nation that you choose (England, Brazil, etc...). This roster will have random bronze/silver/gold players initially (depending on their rating, gold being the best), and you can earn more players by opening packs (that you can get either free for completing objectives and playing certain game modes inside ultimate team, like squad battles and division rivals, or buying with coins, that you earn playing the game) or buying from the transfer market, which is an online market where people can sell their players to other FIFA players using in-game currency, which is FIFA coins. You can get FIFA Coins by playing the game (and selling your players) and that is the only way to get it. The currency that you can get by using real money is FIFA Points, which is an alternative way of opening packs, and thats it. You cant use those FIFA points to buy players directly.
That being said, playing about 3 matches, either online or single-player is enough to get you an all-gold team. You need 18 players to play a match (11 on the first team + 7 on the bench), and you get waaay more than that with the initial roster that you get by creating the club. Also, you can play any player on any position. So, whatever he did, he definitely has more players to put into his team and play even a single-player match and be able to purchase another player for that position.
Also, even if he managed to sell all his initial roster players, he can delete the club and create another one any time he wants.
Sorry if my english is kinda confusing, any questions feel free to ask
