The Frenchman made an instant impact after coming off the bench to score the winner in his first appearance since re-joining the north London club on-loan from MLS side New York Red Bulls.
The goal took Henry’s tally to 227 for the club and he believes the efforts of himself and Colbert have been rewarded.
“You always think that [you can still do a job], but whether or not you do always remains to be seen,” said Henry. “I just said to Tony Colbert [the fitness coach], 'look, you have to get me ready', and he did."
The 34-year-old's performance at the Emirates will no doubt have fans clamouring for the forward to start in Sunday's away clash with Swansea, but Henry insists he is not yet ready to complete a full game.
“I am nowhere near a 90-minute game but he did everything for me to be able to help.
“You are always going to get what you deserve if you work hard. That has always been my philosophy in the game; you have got to work hard. I would rather have the guy in my team who tries any day than the guy who doesn't want to show up. That is my mentality.”
