Chelsea's decision to bring their substitute goalkeeper on against Liverpool is not the first time the west Londoners have done such a thing in the Carabao Cup final.
Edouard Mendy, who was exceptional in between the posts to keep a clean sheet against Liverpool for the best part of 120 minutes at Wembley, was taken off with Kepa brought on following his performances in recent shootouts.
However, the Spaniard skied the decisive spot-kick as Liverpool won 11-10 in a dramatic match in the capital.
