Because he doesn't play there for us! He doesn't play with that freedom to push forwards & ping forwards passes.
Our system is basically geared towards the midfield firstly sacrificing itself for the front three, & secondly them doing the same to create space for the full backs to push up the pitch.
I sometimes wonder how many of our fans actually understand any of our football.
I don't think it's that weird to discuss it, though. If Fabinho sits, then it means at least one of Henderson or Wijnaldum could play a more attacking game. Milner did it recently.
And Henderson was great when he came on.
