The 26-year-old striker missed a penalty before claiming a double in the 5-1 Boxing Day demolition of nine-man Stoke to take his tally for the season to 10.
He ended a five-game wait for a goal since his header against Norwich on November 23.
Loic Remy: "It's true, there's a moment when doubts do start coming into your head, but I wasn't too worried. I knew it would come.
"I wasn't sure when it would come back, but I knew it would come. I play in this team and I get fantastic service.
"People always give me great balls into the box, so I knew it would come straight back.
"It's a good example for kids watching, that in adversity you have to be able to react, you have to be able to face up to these difficult times.
"But I got those two good goals and hopefully over the rest of the season, I will be able to get some more.
"Given the context of the game - two men were sent off, they went down to nine men - we had to go out there, we had the chance and we took that chance.
"But when you look at the match, we knew we really had to go out there and earn those points and that's what we did.
"Thierry Henry was one of my idols when I was growing up and it's quite a special match for me, I have to admit.
"But you need to remember that every game is important for us, especially these massive games like on Sunday where you have got two really top teams going against each other.
"That's where you see the best and the men sort themselves out from the boys, so it will be a good test for me.
"I know it will be a battle, but I think we can go out there and it would be a fantastic Christmas present for Newcastle fans."
