By your own previous descriptions of Wijnaldum's play though, we're missing him providing the link through advanced midfield areas to move the ball forwards. We're not playing neat passing triangles through midfield; and while that was understandable in Coutinho's absence (the reason discussed then being that Gini was struggling to emulate Coutinho's role), we've not seen him successfully back to his own role against Newcastle - admittedly, it's a minimal sample size. On Sunday, our means of playing the ball forwards was a) give it to Coutinho, b) play it wide, c) go deep to one of the front three.
The biggest problem (creatively) in recent games has been the tempo of passing in moving the opposition around. Too slow, too sideways, too predictable. Whoever's in the #8 role needs to provide that function, linking up with Coutinho and Firmino in that central attacking triangle, to pull the opposition out of shape and create it for Mane/Salah. It's odd, in that we (or he) don't appear to be playing to the player's strengths.
I get the importance of space, as well as the ball. Wijnaldum (at the moment) needs to remember the ball is important too; or someone else (almost certainly not Can) will be doing it instead.
Agree with everything you said about our tempo and the actions (or lack of) of the #8. Against Spartak I noted how Can didn't link up with any of our front 4. It was the same here with Gini (bar Salah who he played in a few times during the game). But he didn't link up at all well with Coutinho. More worryingly I only saw him as a passing option when Migs, Gomez, Lovren or Matip had the ball. When Henderson/Coutinho had the ball, his movements were in relation to opening or closing spaces rather than offering himself for a pass.
I agree with what I stated about his role in the absence of Lallana. Nobody is perfect in our midfield at the moment. Unless you see their roles as being similar to Dortmund where Coutinho is the Kagawa with almost complete freedom with Bender & Gundogan existing to give him the platform to have that space and linking the play. In which case Coutinho is doing fine, Henderson is linking but not giving the stable platform. Gini is giving the platform, but not linking (but has in the past). Can is doing neither. Historically, Milner was similar to Gini now in giving a stable platform but struggled to link play. So whatever combination we are trying at the moment isn't working.
So my comment was more about how the players are trying to solve the problems that are appearing. Gini seems to be trying to close up spaces. Henderson seems to be running a lot to cover more ground because of the spaces.
I was tending to watch more off the ball than on the ball with the game at the weekend with our midfield - as I think off the ball you see more of the problems. So I can tell you what Gini is doing, I don't know if it's instructed, the correct thing to do, or if it is contributing to the problems.
Off the ball he was trying to focus on compactness and moving in relation to Henderson. Last season he was moving in relation to Lallana - thus becoming the link man between the back 6 and the front 4. So when Henderson was stepping up into midfield - e.g. the Newcastle goal, he moves to become the #6.
At other times he was moving in relation to Atsu off the ball - positioning himself nearby to deal with his agility and pace threats as Gomez so far looks ill equipped to deal with such a player 1-v-1. There were two good examples where this prevented counter attacks through Atsu when he got the ball in behind Gomez.
Another good example of something he was doing was moving in front of Atsu when Coutinho was on the ball deep, then narrowing in behind another Newcastle player. This makes him unavailable for a pass, but also means he is now being marked by 2 players creating a free player elsewhere - in this case Gomez as when Atsu would track him it was opening up Gomez on the right flank for an easy pass.
What he wasn't doing was moving in relation to the ball - which I know is important for Rodgers sides. He needs to move to open up an angle for the pass. What I don't know is if moving to open up space for passes is important enough? Why he isn't getting on the ball more himself? Is he purely playing the game in terms of space at the moment? Is this instructed to stop the holes appearing that we have seen all season? Is it working aside from the goal?
Basically... I'm looking at his function in a unit rather than looking at his numbers in isolation, which are shite. Based purely on those numbers, you wouldn't want him in the side. But given he is playing, let's assume Klopp is happy (enough) with him and work out what he is doing off the ball that is contributing enough to keep him in the side. Those are the things I see him doing which have no statistical value. Even on the Atsu counters he didn't make a tackle or win the ball, just chased him, forced him to turn around and the ball went backwards ending the counter. A statistical value of 0 - and yet without it would could have had another Vardy goal like we saw at Leicester where the winger gets away from Gomez and crosses.
The alternative possibility is that he isn't doing enough, Klopp isn't happy with it - yet is the only midfielder we have who thinks of space first (Although I think Milner does as well). Dropping him causes a problem as the alternatives (Can, Grujic, Milner) would cause us further problems in terms our compactness which is the reason our midfield is being too easy to play through at the moment. This results in him being practically undroppable despite his performances being way below what is required.
