And what a debut it was! A goal after just 12 minutes and another helter-skelter match at the Lane that frayed the nerves but, thankfully, the seven goals on the day were this time tilted in our favour.
"It was unbelievable, to be honest," reacted the striker afterwards. "I was watching the game the other night against Man City, but this time we got the luck that we deserved. I am so happy we got the three points.
"Out there you can imagine how my heart was going, I thought we played quite well but we needed the bit of luck we got with Gus' goal at the end. Everyone is delighted."
The 21-year-old's delight was naturally increased by the fact he got off the mark so soon and removed the pressure normally heaped on strikers involved in high profile transfers. It was something not lost on Jermain as he confirmed the significance.
"I think it is really important, to be honest. It is all I wanted to do, I didn't even sleep last night as all I was thinking about was scoring here. It happened for me," he added, before agreeing with Clive Allen's earlier assessment of him as a forward that comes alive in the area in strikes the ball early.
"Shaka Hislop is not too happy with me, but I have learned that over the years. If you hit it early the goalkeeper can't get set and I am so glad it went in."
