亚冠联赛是什么赛事啊英语

The Asian Champions League is an annual continental club football event organized by the Asian Football Confederation (AFC). It is the premier club tournament in Asia and a major tournament on the global stage. It was first held in 1967 and has since expanded to involve 32 teams from across the continent.

The tournament is played over two stages， with teams being divided into eight groups in the first stage and then the top four teams from each group progressing to the knock-out stages. The final is a two-legged affair， with the winner determined by a combination of points， goal difference and away goals. The winner of the Asian Champions League qualifies for the FIFA Club World Cup， while the runners-up qualify for the AFC Cup.

The tournament is contested by teams from all over the continent， including clubs from Japan， China， South Korea， Australia， Saudi Arabia， Qatar and the United Arab Emirates. The competition has been won by clubs from a variety of countries， with Japanese clubs having won it a record nine times， followed by South Korean clubs with seven titles. The reigning champions are Al-Hilal of Saudi Arabia， who won their second title in 2019.
