It is true that Barcelona concede many goals, they score a lot, but they concede too, but one thing they did very well this season is outscore their opponent, so they go like, you score, but we are gonna score more. Though that didn't work against Inter because the Italian team scored more goals than them and went through.

That said, i don't expect to see too many goals in this CL final, it is usually a tight game and could even be decided by just a single goal. I find it very hard to pick between PSG and Inter, but i am going to put my money on Inter because i believe this is their year.
