Researchers have found a racial bias by match officials in the country’s top league, but say it could be linked to crowd pressure

Referees in Italy’s top football league give more yellow and red cards to Black and darker-skinned players than to their light-skinned teammates, research shows.

Officials in Serie A awarded an average of 20% more fouls per season against darker-skinned players from 2009 to 2019, with 11% more yellow cards and 16% more red cards.
