I kind of agree but in all honesty Henderson and Milner can both fill in very well in that position, CDM, so I don't see that as any big priority, replacing Gini is though and as I've said Odegaard would be perfect for that role, plus give us a bit more creativity.
Far from the DM discussion, I think (that's just me guessing) that the idea in Klopp's mind and his staff's mind is to slide Jones into that role (Gini's). He may not be a carbon copy of Gini (no player is a carbon copy of another and thank god for that) but he is versatile enough to play on either side of the DM in our system and has plenty of room to develop if given the minutes.
If we are strictly talking Gini's replacement (in terms of filling a spot), I'd rather we go for someone who can do what Keita was brought in to do but can't do because he is out all the time. The idea that we are going to buy a conventional AM (like Odegaard) and stick him in the midfield of the current formation we use without any consequences is optimistic at best.
Conventional AMs like Odegaard won't track back (throwback to Countinho) and even if they do you lose a lot of their potency by forcing them to track back deep into your own half and dropping them into dog fights. Some of those also don't have the required mobility and stamina to be thrown into a creative wing role. This is why bringing in somebody like Odegaard implies switching to a 4-2-3-1 or something to accomodate the guy. This is also why Keita was brought in. You still need that creativity but you need a different type of supplier, namely a high octane box to box who has a 3rd lung and excels defensively and offensively and can carry the ball straight into the opposition's back line.
I'm not saying it's impossible tho since last summer there was clear signs that Klopp was looking to implement the 4-2-3-1 in order to switch between it and the 4-3-3 (eventually at will). In that spirit buying a conventional AM would make more sense but then you would have to think about the price tag and wage of that player vs the amount of games you are going to give him. Makes no sense to get bullied by Madrid into paying 50M or 60M for somebody who can only play when we're fielding a 4-2-3-1. I'd rather go and get somebody in the style of Sabitzer, Milinkovic-Savic, etc (just dropping names based on my initial knowledge of those players just to give an example or two of the style, I didn't really check their price tag, injury record, etc.)
