Five Barcelona players are risking their third caution in the Champions League and could be suspended if the Catalans reach the quarter-finals.
Perhaps most notable is 16-year-old Lamine Yamal who has made 42 appearances for Barcelona this season and is set to become one of the best prospects in world football.
Ronald Araujo with Frenkie de Jong and Ferran Torres and Joao Felix are in the same situation with the teenagers with the last two contributing six goals and two assists between them in the Champions League this season.
De Jong started the match 4 times with Araujo being the most used of the 5 players with 7 starts ending 90 minutes on each occasion.
Andreas Christensen and Sergi Roberto are suspended for their upcoming game against PSG in Spain.
The Catalans will face Atletico Madrid or Borussia Dortmund if they cross.
