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.
Yeah, this final is different from last season's Real Madrid versus Borussia Dortmund final because it was already obvious that Real Madrid is gonna win but in this season's final between Inter Milan and PSG, technically it looks like Inter Milan will win the trophy but in reality you will see a balance between both teams and if you observe PSG in the domestic games you will see that they no longer put much interest ever since they were declared title winners but Inter Milan is stressed such that they are trying to win the Scudetto and the Champions League which has made most of the players to experience fatigue and it may likely affect their gameplay unlike PSG that are no longer struggling for anything other than waiting for the final day of the Champions League to display their talents. However, the strength of both teams are equal hence the reason why the bookies gave them almost same odds but before the matchday, the bookies must have figured out the stronger side between both teams and give them the favorite odd.
