It seems likely we will have to sign some English players soon. We have Jones who is 21 in the next couple of years, Kelleher (home grown), Gomez (home grown), and Trent (home grown), and then Hendo and an aging Milner, as well as the non-influential Ox. That's already one gap, which could be 3 by next season. We will need to buy English players for sure, so I see why we are after Bowen, but I hope we can find better value
I've been thinking about this, and I think frankly we should be fine - we have Kelleher, Gomez, Rhys / Nat, Trent, Henderson, Jones, Elliott. That's 7 players who I think are good to be here for at least another 3-4 years.
Not counting Milner as he probably retires next year, and not counting Ox either as I expect he'll be moved on in 18 months.
The more important thing is that you need to keep trimming players from your 17 member foreign quota. As long as we manage to offload the likes of Minamino, Origi and Adrian, we should have enough space for new foreign player signings. Also worth noting, it's really not necessary to register the full 25 as long as you have 3-4 good u-21 youngsters who will play a part in the first team setup. That's typically been a feature of Klopp's squad building, and the academy is presently brimming with talent. We should be in good shape there.
As for signing English players, I think signing them in the 21-25 age bracket from other PL teams is basically getting shafted for value. Players like Ben White who've achieved literally nothing going for 50 million tells you all about that.
The best bet is to continue signing them in the 15-18 age bracket (which we've regularly been doing), and occasionally seeing if there's somebody in the 18-21 age bracket worth buying for a reasonable fee.
I would have thought someone like Michael Olise would've been worth going for given that Palace signed him for just 8 million.
Other players I'd keep an eye out for are Noni Madueke at PSV (though he might soon be expensive), maybe Hudson-Odoi if Chelsea get rid of him. Then there's Jayden Bogle at Sheffield, who'd be a pretty interesting backup for Trent at RB - he seems super talented offensively. I'm sure there's a lot of other young talent in the Championship worth considering too.
