Defenders Dean Huijsen and Alvaro Carreras, along with midfielder Aurelien Tchouameni, are all one yellow card away from missing the second leg against Benfica. All three regular starters must avoid receiving caution in tonight's match at Estadio da Luz.
The disciplinary concerns add pressure to Real Madrid as they seek to bounce back from their 4-2 defeat to Benfica last month. A win tonight would be crucial for their Champions League campaign.
