Nations to FIFA 23 Coins Watch means that any player with an Ones to Watch card whose country is taking part within the World Cup will receive a one-time in-form upgrade when their team win a game within the event. The Erlings are having a difficult time on this particular front, according to reports due to Norway's lack of participation. ('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 require selection for their national team to get the upgrade. So when Gabriel Jesus somehow doesn't make the Brazil squad and his countrymen pick up an upset in Qatar then the Arsenal hitman will still get an additional +1.
In the end, it's worth mentioning the fact that Ones to Watch players do not get upgrades based on other promotional cards. If Tyler Adams gets some sort of wild 90+ card during April in an upcoming promotion called Factsmashers or something else the case may be, his OTW will not be upgraded accordingly. (Sorry Tyler. If it makes you feel any better, you're practically everyone's pre-order OTW Pack.)
The unusual market for transfers of last year's behaviors meant that it was sometimes practical and economical to bring in good promo players to your team, even within a few days of their release. It could still be true in FIFA 23, but for this moment, the most popular Ones to Watch players are likely to cost you a huge price. Given that they have currently had no enhancements at all which is why it's difficult to suggest you spend any money for them.
At the bottom of the scale, Nico Schlotterbeck from Borussia Dortmund is currently averaging 14k, which is only 4k more than his discard price. He's a decent starting centre-back, but he doesn't have the desirable 'long running type. despite Dortmund's stuttering form it's not difficult to imagine that he will be a candidate for some of the Wins to FUT 23 buy Coins Watch upgrade in the coming weeks.
