Lille-Lens match classified as high risk by the prefecture. The risk level for the Northern derby has been raised to level 4, on a scale of 5.
The Nordic derby was marred by major incidents on September 19, 2021, when Blood and Gold supporters invaded the stadium, causing 6 injuries. In 2020, Lensois supporters had already entered the Luchin area, the Lille training center, and caused some inconvenience. The Professional Football League then imposed a suspended penalty point on the two clubs.
