The penalty shootout started with both teams' first takers, Haller and Barkley, scoring their respective penalties. It became a little bad for Chelsea then as Azpilicueta had his weak penalty saved and Jovic converted his penalty. Then, once again, both teams' third takers, Jorginho and Guzman, scored their penalties.
Thankfully, then, the Kepa show began as he saved the last two penalties while David Luiz and Hazard scored, to help Chelsea qualify for the final of the Europa League. Kepa was fantastic all game and it was only fitting that it was his contribution which made the biggest impact in Chelsea's penalty shootout win.
UPDATE: Full shootout.
