Central midfielder: Jordan Henderson (Liverpool)
Jordan Henderson is more than Liverpool's captain. He's their midfield talisman, key to dictating their play whilst also important at regaining possession and shielding the back-four.
As he demonstrated against AC Milan in their opening Champions League match of the season, the 31-year-old possesses a keen eye for goal too and can be a huge threat in the air from set-pieces.
Central midfielder: Koke (Atletico Madrid)
As far as underrated midfielders are concerned, Koke is right up there at the very top of the list.
He's been an impeccable presence in midfield for Atletico Madrid for several years and his experience will be crucial in getting one over this in-form Liverpool side again.
He's incredibly versatile, capable of playing across various positions in midfield, while also possessing an expansive passing range, which Koke often uses to create goalscoring opportunities.
