That squad has been poorly mismanaged in the long term and now needs serious work. I have no idea why they praise Michael Edwards as he’s created a time bomb for the next manager.
Can left on a free, Wijnaldum will leave on a free, Lallana left on a free, Milner will retire soon. That’s seriously bad practice to let 4 players you actually want to keep and have value walk out for nothing. They’re left with Henderson (who will now have problems as you’ve said), Thiago (injury prone and no resale value), Keita (terrible buy, plummeted in value, never fit), Curtis Jones (not as good as those leaving), and Fabinho (one of their few prime assets). Klopp will be going back to FSG asking for more money in the summer for two extra midfielders or he risks once again burning out the ones he does have. He’ll be essentially hoping that Fabinho Thiago Keita stay fit and play every game because he’ll only have one or two sub par options to rotate them with.
Upfront is a disaster. Three players on mega contracts all declining, all who either want a move or want a new even bigger contract. All not as good as they were.
In defence they have two good fullbacks but what state will any of those centrebacks come back in? Klopp will again be wanting more money.
Compare that to City who have gradually transferred out even good players for fees (Boateng, Sane, Negredo, Navas, Dzeko Otamendi Angelino etc. and refreshed the squad with younger players Bernardo Stones Dias, Laporte, Sterling Foden.
Even looking at our squad, whilst it doesn’t hVe the same quality right now the long term prospects are better. DCL Richalrison are two of the best striking prospects in the league and could demand a huge fee. Holgate Godfrey Branthwaite are all young at the back. It’s only really midfield where we have predominately older players that may need replacing in the near future.
