Ki has conceded that he did not know about Laudrup's decision until late on, but has declared himself pleased with his performance in Swansea's maiden trophy win.
He told The Scotsman: "I didn't expect it, but I thought it went okay for me. I haven't played there much before but I was happy to do something for the team.
"The boys played brilliantly and I thought we controlled the game. It was a great day. You don't get many chances as a player to play in front of 82,000 fans. It is the first time we have won a major trophy, it is very meaningful for me, for all the players and for the fans because they always support us well, wherever we play.
"This group of players just gets stronger and it has done that through this cup competition. Everyone is working hard and we have had more belief with every game, beating Liverpool, then Middlesbrough then Chelsea in the semi-finals. We will enjoy this."
The Swans success in the cup marked a first major English trophy win for a Welsh club since 1927.
