People will look for any advantage they can. From Fifa 12 to Fifa 18 it was almost always Real Madrid. Sometimes Barcelona sometimes Brazil, and rarely another team. The great thing about Fifa is that you don't need the best team to win, (although it puts you at a slight handicap choosing another team,) You can beat any team with lesser rated players.
At least back then it used to try to matchmake teams with similar star levels so AFC Wimbledon couldn't play against Arsenal.
It's annoying but it's always been like this.
