Mitchell will begin his role as Newcastle United’s sporting director immediately and will have his full focus on helping the club navigate the summer transfer market. The club will already have their plans on who they want to sign this summer, but Mitchell’s appointment will add a new dynamic to their window.
The 42-year-old brings with him a wealth of experience working in not just England, but in Europe and in the Red Bull system - one that is famed for its talent acquisition and development programmes.
Here, we take a look at 14 of Mitchell’s best signings during his time in the Red Bull system, MK Dons, Southampton, Tottenham Hotspur and AS Monaco:

8. Dele Alli (MK Dons and Tottenham Hotspur)
Alli came through the ranks at MK Dons under Mitchell’s supervision. He was then signed by Spurs in 2015 before playing a key role under Pochettino at the club. His career hasn’t panned out the way many would have expected, but it’s easy to forget just what a talent he was after bursting onto the scene. | Getty Images
