Wins to Watch means that when a player's team wins three games out of the next eight FUT 23 Coins domestic matches (starting Sept. 30) They will be awarded an additional one-time stat upgrade equivalent to a similar in-form. So if Man City win 3/8 games, Haaland gets another +1 over and above the in-form updates he receives. (Lol 'if'.)
Nations to Watch means that any player who has a Ones to Watch card whose country is participating at this year's World Cup will receive a one-time upgrade to their in-form if the team they represent wins at the World Cup. It's been a tough time for Erling on this front, it seems due to Norway's absence from the tournament. ('Tough times for Erling' is not something we expect to write on many other occasions this year/decade/millennium.)
Plus, Nations to Watch players don't even need to be chosen for their national team in order to get the boost, so if Gabriel Jesus somehow doesn't make the Brazil squad and his countrymen get victory in Qatar then the Arsenal striker will still receive an additional one-time +1.
Also, it's important to mention that Ones to Watch players do not get upgraded based on other promo cards. If Tyler Adams gets some sort of wild 90+ card in April in the form of a new promotion known as Factsmashers or something else it is, his OTW is not upgraded as a result. (Sorry Tyler. If this helps you feel better, you are in virtually everyone's pre-order OTW packs.)
The unusual market for transfers of last year's manner of operation meant that it was sometimes practical and economical to bring in good promo players to one's team even within a couple of days after they came out. This could prove to be the case with FIFA 23, but for currently, the best Ones to Watch players are likely to cost you a substantial premium. In the event that they've had no enhancements at all It is difficult to recommend spending coins on them.
On the less expensive end of the spectrum, Nico Schlotterbeck from Borussia Dortmund is selling for around 14k coins, which is only 4k higher than his price to discard. He's a decent starting centre-back, however he does not possess the desirable 'Lengthy running style'. despite Dortmund's poor form, it's not difficult to imagine that he will be a candidate for the Wins to Watch upgrade in cheapest FIFA 23 Coins the coming weeks.
