I'm not entirely sure Shaq & Keita not playing is all about them.
I think Klopp has taken the attitude over the Utd & Everton games that they could hurt us & a loss would be potentially catastrophic, so 'played it safe'.
I think not picking either of them or even using it as subs says more about his mindset currently.
His post match comments about it not being time to risk going all out attack back it up too. I hope he has a time in mind to do just that & that time is now.
It's a high stakes gamble, & I don't agree in the slightest, as on paper, makes perfect sense, but the way those games went it was clear taking a gamble & attacking could easily have gotten the points.
Which leads on to a side discussion (probably for another time) about one of Klopp's biggest issues for me, in that he/we under him, find it very difficult to switch styles & change pace once we start a match in a particular manner.
