I think you're safely through mate. A lot of people on here are completely missing the fact that Klopp is excellent in double-legged ties and his ability to manage a team to dominate in 'spurts' contributes massively towards it.
If the tie was the other way round and we were 3-0 up for example, I'd fancy you more than the 2% I fancy us in this tie now.
I like Klopps management style and the way his teams - Dortmund v Madrid for example, you lot v us and dortmund etc - can score multiple goals in a short space of time in a game you aren't actually playing well in or controlling at all.
Either way, I think Liverpool will be a serious team to beat if Keita, Jorginho and another centre half are brought in in the Summer. I do however disagree with your point about another forward, everything is fine for you now and your front 3 are exellent, but we have 2 options in Jesus and Aguero that most teams would die for, and are still woefully short if one is out or suspended. You looked pretty ordinary Saturday without a senior focal point and Firmino can't play every game if you want to compete consistently next year
