"Wins to Watch" implies that If the FIFA 23 Coins player's team win three games in the next eight domestic games (starting September 30), then they get an additional one-time boost in stats similar to an in-form. If, for instance, Man City win 3/8 games, Haaland gets another +1 on top of the updates to his in-form He receives. (Lol 'if'.)
Nations to Watch means that any player who has a Ones to Watch card whose country is involved within the World Cup will receive a one-off in-form upgrade if their team wins a match throughout the match. It's been a tough time for Erling on this particular front, according to reports due to Norway's inability to participate. ('Tough times for Erling' is not something we expect to write on many other occasions this year/decade/millennium.)
And, even better, Nations to Watch players don't even need to be chosen for the national team to get the boost, so if Gabriel Jesus somehow doesn't make the Brazil squad and his countrymen get an upset in Qatar, the Arsenal striker will receive an extra one-time +1.
It is also important to mention it is important to note that Ones to Watch players do not get upgrades in conjunction with other promo cards. In other words, if Tyler Adams gets some sort of wild 90+ card in April as part of some new promo known as Factsmashers or whatever the case may be, his OTW will not be upgraded accordingly. (Sorry Tyler. If it makes you feel any better, then you're the pre-orders of everyone's OTW pack.)
The unusual market for transfers of last year's manner of operation meant that it was typically practical and affordable to add good promo players to one's team, even within a few days of them releasing. That may yet prove to be true in FIFA 23, but for currently, the best Ones to Watch players are likely to cost you a substantial cost. Given that they have currently had no enhancements at all, it is hard to suggest spending coins on them.
At the lower end of the spectrum, Nico Schlotterbeck from Borussia Dortmund is hovering around 14k coins the price is 4k higher than his price to discard. He is a decent starter centre-back, although he doesn't possess the well-known 'Lengthy running style' FIFA 23 Coins for sale . despite Dortmund's slow start, it's possible to imagine him securing the Wins to Watch upgrade in the coming weeks.
