After reading some of your replies, it seems you really want PSG to win the UCL title. 
Although PSG is in top form, beating the more experienced Inter team seems impossible. Experienced teams always find a way to beat their opponents. Last season, for example, Dortmund looked eager and ambitious to beat Madrid. However, Dortmund lost their spirit after Madrid mounted a more consistent attack, and Dortmund ended up losing. The same could happen in the PSG vs. Inter Milan match.

This kinda pointless when you compare PSG vs Inter game to the Dortmund vs Madrid game. Almost anyone rooting to the PSG to win its first UCL. They have solid squad, good in attack and defense. They have also pretty good manager behind them. So, their chance is there.
There is no also a significant move in the odds happens from PSG or Inter. It means bookies rated those clubs are equal. That game is totally different with Madrid's game, which is a one sided game.
