Former Chelsea youngster Cameron McGeehan crashed home a last-gasp spot kick on Monday night to earn the Canaries a slender 1-0 lead against the holders for the second leg return at Stamford Bridge on May 13.
Over 20,000 fans were at Carrow Road and Adams said: "I think he was there until he was 14 and he is still a big Chelsea fan. He is always watching Chelsea television and this is a dream come true for him. He was desperate to win the game and took the penalty with great aplomb to smash it into the top corner.
"He'll probably have a sleepless night now. I was confident when he stepped up. He wants to take penalties, he has always taken them and I think that is probably the best one he has taken. It was never in doubt and at such an important stage of the game. They've won it I think three times out of the last four and they are a fantastic football club. They have excellent players and I am delighted to take that one-goal lead to Stamford Bridge."
