Wow. Opinions eh?
I know, right? To be fair, I didn't watch most of the first half and wasn't that concentrated for the rest of it. Second half I was paying a lot more attention.
The reason I say what I say about City is that Milner - for all his excellence - has no press resistance. And we saw it again last night. Sure, not a great ball from Moreno, but in that situation, under pressure, Milner has few tools in his locker and ends up losing it. Keita's the exact opposite. There were a number of runs/situations and passes where he somehow found space where there was none. And up against a very good pressing team.
It's not that Milner did terribly - though I thought it was a game that really highlighted his weaknesses, especially in a midfield 2 (but then to the extent that's true it's on Klopp, not on Milner) - it's that what Keita can bring is one of the most powerful attributes a midfielder can have - the ability to turn the opponents pressure into our space.
It's exactly that which I thought we seriously missed against City. We only had Gini with ability to receive, move and play through tight spaces. But the difference between Gini and Keita is that Keita's got that wee kick of acceleration and pace to get away - to turn 4 people encroaching on him into 4 people behind him with our trident running at their back 4.
And I thought that situation - a transition through a pressed midfield, leading to our attack running at their defence with a man on the ball to feed it to them - is exactly what we didn't have enough of against City. The one time we did it was Salah escaping their press with a lovely turn, who then set Mane free for what we were really unlucky was not the opening goal.
But neither Hendo nor Milner can or ever will provide that. Keita did it 3 or 4 times in one half alone, and, I repeat, against a genuinely decent pressing side with a strong midfield. And he did it without the support of a 10, a 6 or, to an extent, even his midfield partner.
EDIT:
This is not to say I'm right and your wrong - my first comment was 100% genuine. I just wanted to explain where I'm coming from. I think I can see where others are too - he does seem to be in his shell a bit, he has misplaced more easy passes than you'd expect, he has seemed passive at times where you'd maybe have expected him to be dominant...
I'm just a lot more excited by the positives I've seen than the negatives. The latter strike me as a matter of confidence, where the former strike me as gold-dust in terms of top-level midfields.
