Chelsea suffered their 17th defeat of the season on Wednesday when they fell to a 2-0 loss to Real Madrid. The Champions League holders ran out comfortable winners in Spain thanks to goals from Karim Benzema and Marco Asensio.
The Blues now face the tough task of overturning a two-goal lead at Stamford Bridge next Tuesday if they are to progress to the semi-final after yet another difficult 90 minutes in the final third.
Raheem Sterling and Joao Felix both squandered big chances in the first-half before Mason Mount was unfortunate not to grab a consolation in injury-time.
