Pochettino has not done it alone. When he was lured from Southampton he became Spurs’ fourth manager in five seasons and that had to stop. By giving the Argentinean a five-year deal it looked like Spurs were finally making a public statement: here was a manager they wanted to invest in by affording him the time. They have a state-of-the-art training ground. So exploit that, also, by getting a training ground manager which is what Pochettino is - as was his predecessor, Andre Villas-Boas, of course.
