I get that. But look how he persisted for Keita and Virg despite challenges. He dropped Fekir cold.
Again, there were extenuating circumstances as to why he dropped Fakir, but even if there weren't the fact that he went for him is a clear indication that he wanted a player of his skillset. Klopp is not in the habit of going for a player or type of player and then suddenly realising that he doesn't want that type after all. He and his team have a solid plan in mind.
So the indication is what kind of players they go for, rather than which are successful, I don't really know how else to say this. However:
He doesn't buy for numbers but he buys to expand where they can or how they can play. So you are saying that he bought the others because he was unhappy with what he has. But I think he puts the challenge to these new players to add what they can AND do what Gini, Hendo, Milner can do. Maybe that is why Shaq is not playing so much yet Keita started matches early after he arrived. Actually, Gini came as a wide forward and added to his game under Klopp to the point where people don't think he is an offensive player anymore.
No I haven't said that at all, and now I see where there may have been a misunderstanding. I believe Klopp and his team have a comprehensive plan which includes the skillsets of all the players they have bought and tried to buy.
Add them together and you get an inkling of what the full plan involves. It involves what Gini brings and it involves what Keita and Ox bring and it involves what Shaq was believed to bring. Even if maybe Shaq hasn't worked out that doesn't change the fact that he was bought in because he had something that Klopp and team wanted. Yes he was cheap, but they don't buy for the sake of it, however cheap a player may be.
So add it together and what do we get for midfield? I argue it's something more than than just a power/running midfield. I don't think I'm saying anything controversial here, just backing up what many others have said, which is that it's injuries that have made it seem like Klopp is only after a power and graft midfield.
Without injuries he would have implemented various deployments, including some where the midfield is given more of the creative burden than the fullbacks, as a matter of course, so that the idea that he only wants a hard running power pack would never have taken hold. We'll see how things develop now if they all stay fit.
I imagine Fab + Gini + one other will be the ideal template for bigger games, with slight changes to this for the easier games, with Ox and Keita being that other more often than not, and Hendo and Milner becoming alternatives for rotation. Shaq is less clear because it's not quite clear yet whether he has just been unfortunate or whether he hasn't matched expectations. I see no point in speculating on that.
