Manchester United midfielders Casemiro and Fred are one booking away from missing the Arsenal game on Sunday.
Man United have been overwhelming since the restart of club action, winning seven games on a bounce including a 2-1 win over Manchester City on Saturday.
However, they coul play one of their crucial games against Arsenal this Sunday without some of their important players due to suspension.
Casemiro and Fred have both received four yellow cards in the Premier League so far and it means they will miss the Arsenal game due to a one-match ban if they receive a yellow card against Crystal Palace.
Erik ten Hag will have to decide whether to risk starting Casemiro against the Eagles or rest him for the crucial game against the Gunners this weekend.
