This was Cortese's vision for Southampton, one shared by Pochettino, by defender Luke Shaw, by midfielder Adam Lallana, and by forward Jay Rodriguez and the rest.
Nothing was left to chance. Everything was planned, analysed, discussed. The club's poor away form was one issue. Why did they struggle?
Cortese refused to accept the club's geographical location as an explanation. Players were asked to fill out questionnaires. What time did they wake up at home? What were their habits? Did their children wake them, did the dog? The results were analysed and changes were made.
Saints march to the top flight
Then the 45-year-old focused on the environment. Now, when Southampton travel away from home, the hotel is often booked for two nights rather than one. On the first night, club staff arrive and clean the already pristine rooms. They vacuum up every particle of dust that might cause illness or carry a bug.
Then bespoke mattresses are placed on each bed, tailored to each player. The duvets, the pillow cases and the sheets are washed and ironed by the club, using the same washing powder and the same methods. Wherever the players are, their bed smells and feels the same.
The same applies to food, with the club chef travelling ahead of the squad to each and every hotel. Marginal gains were everything to Cortese.
On the field, the whole team, rather than just the defence and goalkeeper, were awarded clean sheet bonuses in order to promote a team ethic, rather than any division.
