Former Arsenal boss Arsene Wenger believes "social networks" will make substitution decisions in the future, with managers becoming robots.
The Frenchman has aired his fears regarding the direction coaching could be heading as he waits to take on a new job.
Wenger is out of work after bringing a 22-year stint at Arsenal to a close and has been linked with roles at the likes of Bayern Munich, Real Madrid and AC Milan.
Wherever he ends up, he will be expecting to take full control of footballing matters.
That may not be the case, though, for those who follow in his footsteps over the years to come.
