The Champions League has reached the last-eight stage and all ties from this point are being played in Portugal, over a single 90-minute match rather than two legs.
The Italian side ended the domestic season third in Serie A, while PSG won Ligue 1 in France by 12 points – and had a game in hand – after the season was ended early.
Since football restarted, PSG have also won both domestic cups, but were not convincing in their performances.
