"Wins to Watch" implies that when a player's team wins three times out of their next eight domestic ties (starting the 30th of September) Then they receive an additional FUT 23 Coins one-time boost in stats equivalent to another in-form. Therefore, should Man City win 3/8 games, Haaland gets another +1 over and above in-form updates that he gets. (Lol 'if'.)
Nations to Watch means that any player who has a Ones to Watch card whose country is involved with the World Cup will receive a single in-form upgrade in the event that their team win a game throughout the match. It's been a tough time for Erling on this particular front, according to reports because Norway is not participating. ('Tough times for Erling' is not something we expect to write on many other occasions this year/decade/millennium.)
Even better, Nations to Watch players don't need to be picked for their national team in order to be upgraded, meaning that when Gabriel Jesus somehow doesn't make it into Brazil's team, and his countrymen win victory in Qatar however, the Arsenal striker will still receive the +1.
It is also important to mention it is important to note that Ones to Watch players do not receive upgrades in conjunction with other promo cards. Therefore, if Tyler Adams gets some sort of buy FIFA 23 Coins wild 90+ card in April , in an upcoming promotion called Factsmashers or whatever you're looking at, your OTW will not be changed accordingly. (Sorry Tyler. If this makes you feel any better, you're almost everyone's preorder OTW packs.)
