I haven't done the exercise, but I wonder how many of the club badges WITHOUT their name we could identify on sight.
It's probably not you that the marketing is aimed at. A better start may be taking teams from leagues you don't follow and identifying teams by logo there.
But looking at more large teams: Bayern Munich, Ajax, Juventus also provide the full name
Barcelona, Real Madrid, Inter, AC Milan, Borussia Dortmond, and Manchester City abbreviate the name
