Fans from Manchester United and Leeds have violently clashed in the build up to the two sides' encounter at Old Trafford today, which saw chairs and bins used as weapons in ugly scenes in the city centre.
The two clubs are historical rivals and are playing against each other in England's top-flight with fans for the first time since 2004.
With the pandemic keeping fans away from stadiums last season, the two meetings between the two sides was without a crowd, keeping the rivalry on the pitch.
However, as fans made their way to the Theatre of Dreams on Saturday morning, tempers boiled over between the two sets of rival supporters resulting in violent clashes outside cafes and restaurants.
