Lionel Messi, Antoine Griezmann, and Nelson Semedo will all need to be careful in Barcelona’s last-16 second leg against Napoli on Saturday at the Camp Nou.

The trio are all one yellow card away from missing the quarter-finals of the competition should Barcelona make it through to the last eight of Europe’s top tournament.

UEFA confirmed changes to their disciplinary plans this week, announcing all accumulative bookings will expire after the last-16 stage rather than the quarter-finals due to the latter stages of the tournament being changed to single-leg matches.

The changes mean that if any of the trio are booked against Napoli they will receive a one-match ban, but if they all escape a yellow card their slate will be wiped clean for the final stages.

“Exceptionally, all yellow cards and pending yellow-card suspensions expire on completion of the play-offs. They are not carried forward to the group stage. In addition, all yellow cards expire on completion of the Round of 16. They are not carried forward to the quarter-finals.“
