Whilst I don't think I said that in that particular instance, I have been trumpeting that line for a while and I stand by it, I'm pretty sure Fabinho won't operate as a traditional DM as Klopp doesn't like them, he'll attack the ball instead of covering the spaces, he'll push forward and join the attack, as opposed to holding back and playing cautious, he has the physique and ability to act as Henderson has been, but on a much higher level.
What's great though is that even if he's not operating as a traditional DM, he's defensively astute, he knows how to cover the correct spaces, and he knows how to reliver the pressure from the team when under the cosh. He's going to perform that side of his role much much better than Henderson, and that's all we need in my opinion.
