Summary:

• Tottenham have overhauled their recruitment department, hiring Johan Lange as technical director and bringing back Rob Mackenzie as chief scout.

• Mackenzie previously worked at Spurs in 2015-16 before moving to Derby County. He has an analytical background and worked with Lange at Aston Villa.

• The new recruitment team will aim to use data and analysis to unearth undiscovered gems in the transfer market, as well as identify players who fit Postecoglou's system.

• Mackenzie is known for his thorough scouting and for advising against players who won't fit a manager's tactics. Postecoglou is expected to have a big influence on transfers.

• The new setup aims to improve on recent recruitment issues at Spurs. Paratici's role may be diminished with his ban, while Postecoglou drove transfers in his first window.

• The hope is the new team brings efficiency and minimizes risk in signings, avoiding past mistakes like Ndombele. Providing tailor-made players for Postecoglou's system is the priority.
