It must be really scary for seeded teams to have the possibility of getting a draw against PSG now. Liverpool are also among the unseeded teams and their performance in the Champions League has been impressive recently. They play like the opposite of their Premier League performance. I just wish that we wouldn't see a draw like an early finale. It's more enjoyable when we have such matchups while getting close to the end.
This result was not obvious even after the first half - Benfica needed to score 5 goals (at the same time before this game they scored only 3 goals away), but they somehow managed to do it.
By the way, last year Benfica reached the quarterfinals where they lost to Liverpool in a decent fight. Obviously, unlike Liverpool, they have not become weaker over the past year.
As for high-profile couples in 1/8, I'm sure there will be, since out of 16 teams we have only 4 obviously weak ones: Brugge, Frankfurt, Leipzig and Porto. It turns out that in the worst case we will have 4 very strong pairs.
