Around 3,000 Paris Saint-Germain fans made the trip to London this week for Tuesday's Champions League game at Arsenal, including many of the French club's ultras.
Hundreds of ultras, mostly dressed in black, were spotted marching through Highbury Fields a few hours before the match.
New footage has since gone viral on TikTok showing that some of them also turned up outside a local 3G pitch, completely transforming the atmosphere.
The group lit flares and belted out PSG chants behind one of the goals on a small-sided pitch.
