The 26-year-old Frenchman 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.
His superb opener ended a five-game wait for a goal since his header against Norwich on November 23 and he is now relishing the St James' Park showdown with the Gunners after he grew up idolising compatriot and Arsenal legend Thierry Henry.
He said: "It's true Thierry 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."
Remy admits a few doubts had entered his mind during his barren run, but he was always confident the goals would start flowing once again.
He added: "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."
