Kepa, who was drafted into the cup final late in extra time, blazed his penalty way over the bar to hand Liverpool victory at Wembley Stadium last weekend.
Thomas Tuchel's decision to bring on the Spanish keeper completely backfired, with a Liverpool supporter poking fun at the player when he picked up his runner-up medal.
As Kepa collected his medal and walked up the steps a Liverpool fan taunted him as he left the royal box.
In a very, very strong scouse accent, the fan said: "Good job they brought you on there lad, good job they brought you on."
Tuchel, though, refused to blame the 27-year-old for his side's 11-10 shootout defeat to Jurgen Klopp's team.
Instead, he shouldered the blame as he introduced the goalkeeper specifically for the penalties.
Speaking after losing the first major domestic final of the season, he explained: "Do you think we do this and don't talk to the players? The players know the plan and we have done it before
"If you want to blame somebody, blame me; this is not a problem.
"I take the decisions and I don't take them to try to be the hero. Today it took 11 penalties to find the winner. And if you want to blame anyone blame me, there's no problem."
Kepa has only played 14 games this term, mainly featuring in the Carabao Cup. But he was snubbed of a starting spot, with Tuchel preferring Edouard Mendy.
