Liga's squad for the season is allowed a maximum of four foreign players at any one time, and a maximum of eight throughout the season. The team must also register under-19 players to be used in every match of the league season. The jersey numbers in the main table (directly below) refer to the number on their domestic league jersey. For each CONMEBOL competition, Liga must register 25 players, whose jerseys will be numbered 1-25. Because of this, some players may have different jersey numbers while playing in CONMEBOL matches.
