On Sunday, Liverpool won its first domestic final in a decade, 11-10 on penalties against Chelsea.
After all 10 penalties were scored, Kepa Arrizabalaga missed after Liverpool's Caoimhin Kelleher scored.
Kepa came off the bench to replace Edouard Mendy, whose saves kept the final scoreless after 120 minutes.
The move paid off for Thomas Tuchel in the UEFA Super Cup in August, but not for Chelsea, who had already won the Champions League and Club World Cup last year.
Unlike Chelsea, Liverpool kept Kelleher in goal for the cup final rather than Alisson Becker.
"Sentiment should be allowed in professional football," Klopp said. Then we get to the final and I tell him he can't play?
“I am a football manager and a human being, and the human being won this time. He merits it.”
Kenny Dalglish won Liverpool's last domestic cup final in 2012. Under Klopp, Liverpool has won the Champions League and the Premier League.
