Thomas Tuchel made a brave call in bringing on goalkeeper Kepa Arrizabalaga for the penalty shootout at Wembley for the Carabao Cup.
The Spaniard has a great record saving from the spot, having helped the Blues win the UEFA Super Cup against Villarreal with his stops in the shootout last year.
He also stepped up against Aston Villa and Southampton in this competition, making some big stops in the penalty shootouts against both sides.
The decision to drop him altogether was a bold one from Tuchel, with the goalkeeper stepping up in the absence of Edouard Mendy while he was away on AFCON duty.
However, the decision didn't pay off for the German coach, with Kepa unable to save a single penalty before missing his own in an 11-10 defeat to Liverpool at Wembley.
The substitution came as no surprise, as it was a decision made by the German coach last summer for the Super Cup final.
Discussing the decision back then, Tuchel explained his thinking behind subbing him on, saying: "So we had some statistics, we were well prepared, that Kepa is the best in percentage in saving penalties.
"The analysis guys and the goalkeeping coaches showed me, introduced me to the data, then we spoke with the players, that this can happen when we play in a knockout game, and since then they know.
"It's fantastic how Eddy accepts it. It's fantastic how this talk went before the cup game in Barnsley. Since then they know.
"Of course we needed to do what's good for the team. It was necessary. I'm happy that it worked.
"There is proof that Kepa is better at this discipline. These guys are true team players. I am happy for Kepa and happy for Eddy, to have a goalkeeper like this, to not show the pride to not step off the field, and is happy to do it for the team, to take one for the team. It's top."
The substitution also comes, somewhat amusingly, at the same stage of the same competition that Kepa refused to be substituted for the Blues against Manchester City.
The goalkeeper famously refused to come off when Chelsea coach Maurizio Sarri tried to bring on Willy Caballero for penalties back in the 2019 final, though he stayed on.
The Citizens went on to win the trophy that year, though Tuchel will be hoping the outcome is different this time around at Wembley.
It marks a difficult result for both the goalkeeper and his manager, after a positive spell in a Chelsea shirt.
