Here's Liverpool. Not seeing it here, either:

There is an 18 year old who played, but nothing on his player page indicates that he is an academy player. His wiki page indicates that he is with the senior team. https://en.wikipedia.org/wiki/Curtis_Jones_(footballer)
And here's Palace, which I randomly picked from mid-table. Not there:

I don't know what else I'm supposed to look at. I'm certainly not going through every roster in English soccer.
