As many as seven players could miss the second-leg of the Champions League clash against Real Madrid at Stamford Bridge if they pick up a yellow card tonight at the Santiago Bernabeu.
Chelsea goalkeeper Kepa Arrizabalaga is among those who could serve a one-match ban should he pick up a yellow card tonight.
Enzo Fernandez, Conor Gallagher, Reece James, Kalidou Koulibaly, Mykhailo Mudryk and Thiago Silva are also one booking away from suspension.
All yellow cards expire on completion of the quarter-finals and are not carried forward to the semi-finals.
