I've personally been impressed by KDH this season. For me, he's the one who most closely resembles Drinkwater or Kante from the title winning side ..... great energy in getting up and back and winning the ball and trying to move it quickly.
A little something to consider, which might seem rather out of left field, are Tielemans and Maddison currently weak links in what could be a more effective, fast moving team? Both Vardy and Daka play on the shoulder and need quick ball. Either one partnering Iheanacho might benefit from a faster midfield of KDH, Praet, Mendy, Soumare, Ricardo or Barnes. Is that what we need to help us get out of the relegation fight?
