Lee scored the winner against Birmingham on Saturday, and told the club's official website: "Kevin Davies was also going to win the header, so when it was played across I knew he was going to put the ball where I was moving to.
"It was a great pass and I couldn't miss. I felt like I was flying when the ball hit the net - I lost my mind!
"I feel wonderful. It was a very difficult game but we managed to win and I feel great that we are going to Wembley."
