Liga Mx
In short
The top professional football league in Mexico, consisting of 18 clubs competing for seasonal titles.
In plain words
It is the highest level of football in Mexico. The year is split into two separate tournaments called Apertura and Clausura. The winner of each tournament is decided through a knockout playoff called the Liguilla.
A simple example
A team wins the Apertura tournament in December and then tries to win the Clausura tournament in May to claim another trophy.
Why it matters
It is one of the most popular and watched football leagues in North America. It provides a major platform for Mexican players to showcase their talent.
Easy to mix up
Do not confuse it with MLS, which is the top professional league in the United States and Canada.
