Eyah so sorry about your bet bro, that's how those things happen but I am surprised how you didn't know and didn't expect this kind of result. When a team already has such goal gap in aggregate from the first leg they usually don't play the second leg with utmost seriousness because they know it will be difficult for the opponent to turn things around. Some teams don't even play their entire starting eleven they give chances to the reserve teams so you can't expect them to perform as they should.
I believe you have now learned something and this kind of mistake will not happen again.

I will say a big congratulations to PSG on their historic Champions League victory! Their game play during the competition was spectacular -- they deserved that trophy. Their performance in the final between Inter Milan was a surprising one to watch Btw.

It will be something of interest to see PSG defend their title next season. As for next season's champion league, I guess either an English or Spanish team will win the trophy. The improvement so far in English teams and the Spanish as well is massive, with the recruitment of new star players to their squad, I doubt any other league will win that trophy. These very two nations have consistently produced top teams that have excelled on the several European stages.
