As good as we all know he is, he isn't really what Liverpool are after as far as I can see. At the moment they have four competent CMs in Milner, Henderson, Wijnaldum and Fabinho, but none of them do enough to impact on the game in the final third so picking three from them leaves them a bit over-reliant on their forwards for goals and creativity. Keita hasn't come off yet, Shaqiri has always been hit and miss (with shite fitness) and sadly it looks like Lallana's best days are gone.
Neves doesn't fix that issue for them. You can argue he's already better than say, Henderson, but it leaves them with the same problem, there was a point with us where he'd never touched the ball in the 18 yard box for Wolves except when taking a penalty (don't know if this is still true).
