In addition to the coaches who control the team like playing games, the 4.0 revolution in football also creates a whole new career: Data analysis experts.
People who hold this position in the clubs receive extremely high salaries despite working almost no experience. Their origins before they came to football are also in the sky including freshmen, editors, reporters, managers of a group of young football lovers online, even the unemployed.

Unpredictable consequences
Billy Beane, a pioneer in applying data analysis to baseball, and later football, acknowledged that his success came from an unspeakable moment.
The winner of Athletics’ record of 20 consecutive wins at MLB (American professional baseball) is Scott Hatteberg, a professional who dropped the ball but he hit the ball directly on that day! The thing is, Beane’s share is not ignored by the football management.
Clubs continue to apply rigid and mechanistic data analysis to sports, with young professionals who are ignorant of football. From data analysis, a few of them gradually assumed the task of recruitment and human resource management. The consequences start from there.
Villas-Boas’s two-stone interception style is the typical product of such a feared loser. At any club, he lost very little, but in return, drew a lot. Therefore Villas-Boas can only succeed in Porto and Zenit, the clubs have a much stronger financial potential than the rest in the domestic league. When moving to Chelsea and Tottenham, similar successes never came.
Another corollary of the deference of figures in football coaching is the extinction of the classic 10 numbers. There are no more people like Riquelme, instead a versatile Eriksen-style midfielder, a player who can play anywhere.
As can be seen, besides great advantages that the technology revolution 4.0 has brought up, there is also the dark side of it in some sports, which include football.
