Manchester city council have said they don't want to "eradicate the city's past" amid suggestions the badges of Manchester United and Manchester City have links to slavery.
The two sides have been amongst the most dominant during the Premier League era, winning 19 titles between them. United's success under Sir Alex Ferguson saw their global brand rise and they remain among the biggest clubs in the world.
City meanwhile have triumphed on and off the pitch since their Abu Dhabi owners arrived over a decade ago. The influx of foreign stars has seen their stature rise, especially with younger fans, meaning both club crests are highly recognisable throughout the globe.
