Michael Obafemi thanked team-mate Nathan Redmond for his help on and off the pitch after becoming Southampton's youngest ever Premier League goalscorer.
The 18-year-old, who joined Saints from Leyton Orient in 2016, marked his fifth Premier League appearance by tucking away Redmond's cutback six minutes after coming off the bench to seal a 3-1 victory over Huddersfield.
Obafemi had already missed a very good chance and went on to see another shot saved by Jonas Lossl.
He said on southamptonfc.com: "It was surreal and I'm thankful to Redders for giving me the assist. I should have scored two or three more but I'm just delighted to have got my first goal.
"I wanted to get the previous chance out of my head straightaway because I knew myself it should have gone in the back of the net. I knew another one would come and I'm glad I put it away when it did.
"Just before I came on, the manager said to make sure I run and do the basics before anything else and the goal will come. All the lads on the bench were saying just show what I can do and that the rest would fall into place."
Obafemi made his Premier League debut against Tottenham in January and was given a first start by Mark Hughes in the previous manager's final game against Manchester United earlier this month.
He impressed before being forced off by a hamstring injury and this was his first appearance since.
New manager Ralph Hasenhuttl has now won two of his first three games in charge, and Obafemi praised the impact of the Austrian as well as winger Redmond, who was the stand-out player on the pitch at the John Smith's Stadium.
"He's changed the whole system," the teenager said of Hasenhuttl. "You can see we are a lot more aggressive and direct and playing higher up the pitch. It suits us and it's getting us results.
"On the pitch, Redders is a close friend of mine and he's always giving me advice before games and even off the pitch as well, making sure I stay grounded.
"This is a first step in my career. I've come a long way since my debut against Tottenham and I'm thankful for everyone who has believed in me and got me back into this position."
Southampton are now three points clear of the relegation zone and five points above Huddersfield, for whom this was a fifth consecutive defeat.
Defensive errors coupled with an impotency in front of goal is a worrying mix for Terriers boss David Wagner, who has been drawing up a wish list for the January transfer window.
Top of that list is surely a striker, with Steve Mounie and Laurent Depoitre having failed to register a single goal between them.
Philip Billing's effort on Saturday, which pulled the score back to 2-1, was only the fourth they have managed at home this season.
Wagner said: "Obviously when you've played 18 games and you have no striker goal, this is not want we like to have. What this means for January, I can't give a serious answer. We have to make sure that we try to do everything to score, strikers or not, in the next game. "
