Big name players like Messi or Ronaldo will remain on the bench or as coaches while humanoid robots will entertain us with their techniques borrowed from real players. The biggest advantage to using robots in football games is the possibility to integrate in a single player all features which were noted by real football players like Messi or Ronaldo.
