Leno and Saka are our only dependables.
But to be fair, Partey, Aubameyang, Martinelli and possibly Gabriel and Tierney all wouldn't look out of place at Liverpool when at their best. We're not that far off from having a really good starting eleven, at least on paper, and we have a good pipeline of prospects, with ESR, Balogun and Nelson looking to be the next ones to break through. Pépé, Saliba and Guendouzi all have a lot of potential as well, even if it hasn't worked out for them so far one way or another.
So I don't think we need an entire new starting eleven as our position in the table would suggest, we just need to cut the squad in half, get rid of the overpayed, aging shitsters like Xhaka, Mustafi, Willian, Özil et al., add two or three top class players, especially in midfield, and make our talented young lads the first choice back-ups. It doesn't sound that hard in theory. And all that would only work with a competent manager at the helm, and I have my doubts that Arteta is that.
