Chelsea reached the UEFA Europa League final after defeating Eintracht Frankfurt on penalties in the second leg of the semi-final in London on Thursday.
The match ended 1-1 with the aggregate scores tied at 2-2, and as both teams held an away goal, extra time was needed.
Ruben Loftus-Cheek had given the hosts the lead after 28 minutes but the visitors struck back at the start of the second half through Luka Jovic after a defensive lapse.
David Luiz and Davide Zappacosta saved Chelsea as they both cleared off the line and it was the Bundesliga outfit who were in the ascendancy during extra time.
