Mason Greenwood burst on to the scene for Manchester United's senior team on Thursday night.
Sure, supporters have been raving about him for over a year now, but it was his ninth appearance in the first-team against FC Astana that truly announced him to the world.
With the scores locked at 0-0, the young Englishman collected the ball on the right flank and delivered a finish that someone 10 years his senior would be proud of.
Of course, it's still early days for Greenwood, but fans will now be hoping that he follows in the footsteps of Marcus Rashford and becomes a regular fixture in starting XI's to come.
In other words, they'll be hoping that Greenwood's performances endures more like Rashford's vs Midtjylland in 2016 as opposed to James Wilson's vs Hull City in 2014.

Greenwood bursts on to the scene
And a massive part of that will come down to Ole Gunnar Solskjaer finding the right balance between giving his experience on the big stage and not overexposing him too soon.
It is, after all, easy to forget that Greenwood is just 17-years-old, which makes him even younger than other 'wonderkids' such as Matthijs de Ligt, Moise Kean or Frenkie de Jong.
Comparing him to those kind of players already seems a little unfair and Greenwood is far better suited to company alongside the likes of Ansu Fati or even his teammate Tahith Chong.
Most valuable young wonderkids
So, in light of Greenwood's success and without drawing some more experienced youngsters into the debate, we've decided to hone in on up-and-coming talents aged 17 or younger.
We're using calling upon Transfermarkt - one of the thorough banks of football data - to achieve this after they ranked the likes of Greenwood by their transfer value in a recent gallery.
It's one of the best ways of assessing just how exciting these young stars are being perceived, so - without further ado - here are the young wonderkids with the highest transfer stock:
20. Killian Sardella (Anderlecht) - £1.80 million
19. Eddie Salcedo (Hellas Verona) - £1.80 million
18. Sepp van den Berg (Liverpool) - £1.80 million
17. Talles (Vasco da Gama) - £1.80 million
