Ki said: "The derby win was a really special game for me and it always is to play in front of these Sunderland supporters. They are always behind us even though we did not deserve it sometimes. They have been great because they have waited for things to turn around and they are now able to celebrate better results.
"I don't know if I will be playing in this fixture next season, honestly. But I am really pleased with all the fans, all the staff and all of the players. I don't know what will happen in the future but at the minute I am very happy playing for this club and with these boys."
