Attempt to update the game. Buriram United have been in FC26 since April 7th 2026. You probably haven't updated it. If the issue still persists, then contact EA or try to get advice from other FC players on reddit or discord.
While true that Buriram United was added two weeks ago, the club is only useable during Kick-Off matches. Everyone has been waiting for a Title Update (supposed to be today, however delayed for some reason) to make available in Manager Career mode as a Rest of World club addition. The club does not appear anywhere in career mode currently.
Buriram United is already in the game but missing from Career Mode. Please add them in the next update. A lot of players are waiting for this feature.
