PSG-Real Sociedad: who is Marco Guida, referee of the round of 16 first leg of the Champions League?. Guida has only refereed seven matches in the premier club competitions.
The 42-year-old official has not managed any match in the final stages of the competition. He was notably in charge during RC Lens' exploit against Arsenal (2-1) and during Manchester United's victory against FC Copenhagen (1-0). He has already refereed PSG despite this lack of European reference.
