Manchester United have set up an online system encouraging supporters to report incidents of racism and other hate crimes.
United’s “See Red” campaign follows Arsenal’s launch earlier this week of an action plan called #StopOnlineAbuse.
United stars Anthony Martial, Marcus Rashford and Fred have all been subjected to racist abuse this season.
Fred hit back saying “we cannot feed that culture” of racism after he was racially abused following his side’s FA Cup quarter-final defeat by Leicester.
Former Arsenal star Thierry Henry recently quit all his social media platforms in protest at the rise in internet abuse.
“We challenge our fans, and indeed fans of every club, to watch this and think about their own favourite memories, their top teams and their most celebrated players,” United group managing director Richard Arnold said.
