Ecstasy and agony are sentiments every supporter has experienced. FIFA.com's latest 'Have Your Say' wants you to concentrate on the latter: What's the most disappointed you've been?

Was it your team losing a game, perhaps a derby, a cup final, a title decider or one in which they surrendered a solid lead? Maybe it was them failing to qualify for a major competition or succumbing to relegation.

Could it be your favourite player missing a crucial penalty or moving to a rival club? Perhaps it was your idol being dropped or retiring.

Whatever moment left you most disappointed, be it due to your club or country, be sure to share it with fans from across the globe. Simply click 'Add your comment' to do so, remembering to keep your posts clean, respectful, on-topic and in English.
