Sound the alarms for Paris Saint-Germain, as the team's fans are in panic mode right now. According to a report, superstar Kylian Mbappe suffered an injury during training ahead of Wednesday's Champions League showdown with Real Madrid.

Now, it's looking like PSG might have to try and advance to the quarterfinals without the stud forward out on the field with them.

This is a massive blow for PSG. Mbappe scored the game-winner in the first leg, with that contest taking place at the Parc des Princes. Now, PSG will head to Madrid to try and beat Los Blancos, but things will be tricky without Mbappe in the mix.
