Eddie Nketiah, remember the name.
With five minutes remaining of Tuesday's Carabao Cup clash with Norwich City and Arsenal 1-0 down, Arsene Wenger threw on a completely unknown 18-year-old to save the day.
And he did just that. Just 15 seconds into his home Arsenal debut and Nketiah poked home from a corner to bring his club level.
It was sheer ecstasy for the teenager, who raised his arms, ran to the corner flag and imitated Kylian Mbappe's famous celebration as his teammates swarmed.
But little did he know, the best was yet to come. Six minutes into extra-time and Nketiah rose highest to head home his second goal of the game, giving Arsenal a 2-1 win.
A brace on your debut in front of 60,000 fans - it doesn't get much better than that.
Wenger was full of praise for the young forward in his post-match press conference, saying: "I felt I was happy for him and the team.
"I know that he can score goals and that he has character. He is not afraid. He can give and go, and once a player has that in his game, they have a chance.
"He has the flair to score, you have to be in the box and he has that. It's not a quality you can teach at that age.
"I liked as well the header he scored. He's not tall, but he got very high. It shows his determination, and shows the guys who want it."
Nketiah looks like the real deal, which makes his journey to becoming an Arsenal player all the more incredible.
As revealed by Chris Wheatley (see below), Nketiah was released by Chelsea at Under-14 level in 2015 due to fears about his "physical presence".
Asked about Nketiah not making it at Chelsea, Wenger said: "I don't know why Chelsea decided to let him go. You see that more and more these days, young people going from one club to another."
Upon being released, Nketiah was snapped up by Arsenal and he's since progressed through the ranks to become an England U19 international.
Chelsea have had a mare and their loss is ultimately Arsenal's gain, which prompted Gooners to troll their London rivals on social media.
Another top talent let go by Chelsea. Nketiah claims his pace and finishing are his strongest assets, which will only excite Arsenal fans about what the future holds for him.
