The whole drama took Inter Milan by surprise that's why they gave up on the game very early because they never saw that performance coming and as a team with so much good performance Inter Milan wouldn't believe they couldn't score a goal and they have to concede 5 goals in a champions League final. Sorry for your loss but watching the game and the performance of Inter Milan you could see that they played everything they have on the game against Barcelona and they got weak tonight and failed to register a goal.
I think it was a very painful defeat for Inter Milan because they conceded many goals to PSG even though I thought Inter could fight PSG and win the UCL title but instead PSG was able to surprise everyone I'm sure many did not expect PSG to win the UCL with such a good performance because as we know PSG players do not look as strong as Inzhagi's squad but it turns out Luis Enrique was able to make his players appear very confident.
