EA SPORTS FC™ TeamHi @rrancan,
There's no way for your opponent to change the stamina of your players. Check if you changed tactics during the game, switching to an offensive mentality. if you did, your team pressed your opponents and lost stamina very fast during the game. Try this strategy only in critical circumstances and for a short period of time.
for more that i like that to be true i itsnt, a couple weeks ago i had the same issue, today (31/05/24) a friend of mine had the same thing, all in UT (Champions or Rivals)
