I dont know for sure but i think the year pakistan won the world cup (1992 i think? In Australia), the duration of the tournament covered most of Ramadan. i clearly recall my dad mentioning that "the players look dry mouthed and hungry, they must be fasting, Allah help them win". even though i was 11 at that time, i do remember seeing Imran Khan looking dehydrated.
Treat others how you want to be treated
