Now Hakim Ziyech's drive is blocked by Raphael Guerreiro. Chelsea have had plenty of half-decent chances.
Reece James finds Enzo Fernandez, who picks out Joao Felix but the Portuguese loanee's shot is easily saved by Gregor Kobel.
Felix's finishing hasn't been great today. Story of his career, a cynic would say.
Niklas Sule gets a bit lucky here. Kai Havertz runs onto Mason Mount's through ball and behind Sule. The Dortmund defender tries to pull his shirt back and then slides in and just about gets the ball in the box. Could have been a free-kick and was inches away from a penalty.
