#1 N'Golo Kante, the playmaker
The French midfielder is not particularly known for his exploits in the final third of the pitch, and although its more common to now see him going forward in this Chelsea set-up, he stepped it up against their Spanish opponents.
N'Golo Kante was imperative in winning the ball in deep positions and carrying it forward or releasing runners. He also was spotted linking play in the final third and making runs into the box constantly. He was a big part of the attacking play in the game which has not always been true of his play in a Chelsea shirt.
On a couple of occasions, he had a go at goal as well in a direct threat to Valencia's defence. He also delivered the cross that led to Christian Pulisic's goal in terms of tangibly contributing in attack.
