Piala Asia
In short
The AFC Asian Cup is the main international football tournament for men's national teams in Asia. It is organised by the Asian Football Confederation and held every four years.
In plain words
It is like the European Championship but for Asian countries. The best teams from across the continent play against each other to find the champion of Asia.
A simple example
Teams like Japan, South Korea, and Australia compete in the tournament to win the trophy. They play matches in a group stage followed by knockout rounds.
Why it matters
Winning the cup proves which nation is the strongest in Asia. It also helps teams gain confidence and ranking points for the FIFA World Cup.
Easy to mix up
Do not confuse it with the AFC Champions League, which is a club competition rather than for national teams.
