Inter are still fighting for their league while PSG have been crowned winners already, they’ll be more prepared and rested for the UCL final to give their best on that day for the title that has so eluded them.
That's an advantage for PSG because they can focus more, especially since Napoli & Inter Milan are only 1 point apart in the Serie A standings after Napoli could only draw against Genoa. In addition, bookies also favor PSG with @2,24 odds, while Inter Milan with @3,25. This UCL final match will certainly be a very interesting match, we'll see what happens later, I hope PSG can win so they can make history for their club in getting the UCL trophy.
