We can easily see international soccer fans at English Premier League stadiums. However, local fans are calling them “Plastic fan” due to their ignorance of the club's ritual or history. Language and cultural barriers have made it difficult for them to learn history and rituals of their own favorite club. We will change Duolingo’s iconic gamification quiz into history of Manchester United which has the biggest international fandom group, so that they can learn English and their club’s history at the same time to become a real fan.
