Henry was in dreamland after coming off the bench to score the winner on his Arsenal return against Leeds in the FA Cup third round.
“It’s kind of weird,” he told ESPN.
“I came back from holiday 15 days ago. I never thought I was going to play for Arsenal again or score a winner.
“I don’t know what to say. I love the club and I hope I can do more.
“I hope it won’t be the last one. The feeling I had when I scored was amazing.
“I rejoined the club as a fan; before I wasn’t. Scoring a goal when you support the team, now I know how some of the guys who played for Liverpool or Man United or Chelsea felt when they scored a goal for the club they support.
“With one opportunity, it’s very important, you don’t know if you’ll have a second. You have to make sure you take it. I took it well.”
