Extra officials may be set to be introduced to keep an eye on crowds for offensive behavior

FIFA has proposed the introduction of extra officials in stadiums to watch out for incidents of racism, plus a two-tier system of sanctions for teams whose followers indulge in discriminatory behavior.

The new officials "would identify potential acts of discrimination with the aim of easing the pressure on referees," FIFA said in a statement on Monday. They would also help gather evidence for disciplinary committees.
