With only a few hours to go until Madrid and PSG will walk out onto the Parc des Princes pitch to battle it out for a place in the Champions League quarter-finals, the visiting side had a rude awakening as ultras from the Ligue 1 outfit showed up at the player's hotel to start the hostilities early.
It followed scenes on Monday in which five PSG players - Trapp, Rabiot, Kurzawa, Kimpembe and Areola - went down to greet waiting fans and join in with some welcome chants as the build-up for the match intensifed rapidly.
However, the ultras have not covered themselves in glory by then moving on to the Madrid team hotel at 01:30am (CET), trying to disturb the opposing players as they rested.

In the video you can see the radicals using firecrackers, horns, megaphones and other tools to create as much noise as possible and thus annoy Madrid who were staying at the Hotel du Collectioneur.
In fact, the situation reached such a boiling point that the French police had to intervene in order to calm both parties, leading to two arrests and no further complaints.
The two incidents - the one with the PSG players and the one against Madrid - has begun to outrage 'Los Blancos', who were already on edge following PSG's outlandish slogan of motivation on their social media page.
It has raised fears over potential security risks and with the game of such a big magnitude, neither side will want non-sporting reasons to detract from the eagerly-awaited spectacle.
