The 29-year old striker, who is on a season-long loan from Aston Villa, tapped home in the 77th minute of the Cottagers' 3-1 home loss to the Gunners but says he would've traded the goal for three points.
"Yeah definitely. I thought the boys in the first half, we did really well, accounted for ourselves really well but it was our own mistakes which cost us really," he told the club's official website.
"All three goals were counter-attacking goals. It's something we have to work on.
"I'm always glad to get a goal but if I had have chopped the goal for three points, I would have took it."
He added: "Someone said to me this morning, to be fair it put me under pressure, 'you know you always score on your debut' and I was like 'OK, thanks'. As I said, it's always nice to get a goal but I would have traded that in for three points."
