Ange Postecoglou has plenty of decisions to make as he reshapes Tottenham Hotspur to his philosophy and the engine room of his team is going to be crucial to how his team performs.
The Australian's midfield set-up is well known in what is mostly a fluid 4-3-3 formation. There is one number six pivot midfielder who operates in front of the defence, collecting the ball and spraying it quickly around to those who get further up the pitch.
Then there is mostly two number eights either side of him who work in box-to-box roles in supporting the striker with runs in and around the box, getting involved in the goalscoring. There can at times be one such number eight and another central player who works as a hybrid between the two types of Postecoglou midfielders depending on the opposition.
