An educated guess at what the squad will look like next season based on Klopp's choices and tactics...
Current squad:
Karius
Mignolet
Clyne Matip Lovren Milner
Trent Lucas Klavan Moreno
Randall Gomez
Henderson
Can
Stewart
Lallana Wijnaldum
Grujic
Ejaria
Mané Coutinho
Wilson Ojo
Kent Woodburn
Firmino
Sturridge
Origi
Ings
There are 5 well-publicized issues with this squad:
- lack of a natural LB
- poor CB coverage (i.e. Lucas isn't a CB)
- lack of cover/alternative for Lallana in midfield
- lack of first-team winger other than Mané
- lack of a clinical striker
James Pearce said recently that he sees a big summer with 5-6 signings and a few "deadwood" leaving.
Considering the way Klopp likes to play, and the 4 issues listed above, it seems logical to think that the following would happen:
- Buy a creative midfielder so the squad isn't overly reliant on Lallana.
- Buy another winger (or two, depending on progress of Ojo, Wilson, etc)
Likely departures (according to Pearce): Lucas, Moreno, Sturridge... Ings' future looks uncertain too.
... meaning that with European football Klopp would probably want:
- Another CB, LB, and striker.
If anyone else leaves (Can? Mignolet?) then that would need to be accounted for too.
In summary:
In's: CB, LB, CM, LW, ST.
Out's: Lucas, Moreno, Sturridge
2017/18 projected squad:
Karius
Mignolet
Clyne Matip Lovren LB
Trent CB Klavan Milner
Gomez
Henderson
Can
Stewart
Lallana Wijnaldum
CM Grujic
Ejaria
Mané Coutinho
Wilson/Kent/Ojo/Woodburn LW
Firmino
ST
Origi
Changes along these lines look pretty reasonable, and address the key tactical short-falls of the current squad listed earlier:
- lack of a natural LB
- poor CB coverage
- lack of cover/alternative for Lallana in midfield
- lack of first-team winger other than Mané
- lack of a clinical striker (to rotate with Firmino)
Those changes also re-balance the squad to keep players (eg. Firmino) having to be played out of position on the wing.
I think most would agree that the First XI is great, when everyone is in form, but lacks the quality to allow the same shape to be kept when there are injuries or loss of form for key players. The suggested changes completely address the squad shortfalls by adding quality where needed by providing balance in the squad depth-wise.
Looking forward to hearing some thoughts, but keeping more focus on the squad and tactics than on transfer speculations.
