They stacked in depth but it's quite clear who are the best players. It's alot of young talented depth players who aren't ready to start on their bench (except old Sterling).
Their defence and midfield is set, and if we bench Lavia they started today because it's big game, for extra attacking player in Neto, then this is imo their best eleven:
That's a very competitive eleven in every position except the already mentionned Jackson. They need a significant upgrade on him. They may think Palmer and Nkunku can score striker numbers, Neto chips in a dozen, but even then it's big improvement for your team to sign extra quality striker. It's clear gaping hole for them.
