Substitute Ki Sung-yueng scored a dramatic game-winner for Sunderland on Tuesday that took the English Premier League club through to the semifinals of the Capital One Cup.
It was the midfielder's first goal since he signed with the club on a one-year loan from rival EPL outfit Swansea in September. He failed to score during his yearlong spell with the Welsh club.
The Black Cats, which are currently sitting at the bottom of the league, were hosting Chelsea at the Stadium of Light when Ki came on in the second half.
The game was tied at 1-1 until almost the end of extra time when Ki collected a pass from Fabio Borini in the left hand corner of the penalty box and drove it into the back of the net in the 118th minute.
"I had never imagined that I'd score a goal in a big match like today when I went on as a sub in the 63rd minute. I want to go to Wembley for the final and score more goals," he said.
