Compare to some of Manchester City's alternates:

                                             The Gay Softball/World Football League look.

The whale sperm swimming in dishwater 3rd kit from 2020/21.

European soccer clubs have this thing for bold vertical stripes. If red and blue vertical stripes don't cause you blindness how about a red and blue checkerboard?

To me, European soccer uniforms are designed by insane individuals.
