Wa alaikum salam,
My son, your future should be Paradise and not a soccer team!
Fasting is a pillar of Islam and no one is expected from it except a traveler or someone who is sick!
It is a major sin to break fasting without a legitimate reason and it is even a bigger sin when you don’t thank Allah for the health and strength He had given you by skipping your obligations for such a thing!
Participating in professional soccer is not recommended if not prohibited due to the many sins involved. Don’t leave your education for something like this! All it takes is one ACL which can ruin the career of a footballer!
