Dortmund fans boo as Reece James and Ben Chilwell take a good while over a free-kick. It's half-cleared to Mykhailo Mudryk, who plays a clever ball in the box but the offside flag goes up against Kalidou Koulibaly.
Best chance of the game for Benfica but Rafa Silva hits the outside of the post after getting on the end of Chiquinho's free-kick.
It was always difficult for Sebastien Haller to score from that position. The alarming thing for Chelsea will be how easy it was Julian Brandt to get into space there.
Some of the Dortmund crowd thought this was in.
