The ref did have an impact in my opinion, not saying it would have changed the result. We had to take probably our best player in Mane off at HT because of it. Klopp basically said the same in his postmatch. But agree with the rest of your post. Can't see them holding us off at Anfield. We will get one or more.
It's only 0-1 .... We got this
I didn't want to face this lot in the draw, because I knew exactly what we would get and we got it. They really are an awful horrible stubborn side to watch and play against, and I think if we were there for the next 3 weeks, we still wouldn't score.
Comparing the task to Dortmund and Barcelona etc is pointless, they play a totally different game to Atletico Madrid. This lot won't move out of their own box, and it's going to be something like the manc games under Mourinho, dour, dull, scrappy, frustrating, just the way they want it. There will be very few chances, so they have to be taken when they come, as it could be another half an hour before another comes. I don't want to say we're out, but I'm not very confident of getting the job done, and if we need to score 3 well...
Just one other thing. This is my least favourite round of the competition, and has been since 2010. The 3 week gap in the ties is crazy, when the later rounds have a one week gap between them, or even just 6 days. The second leg of this game should be next week, and similarly the other 4 ties should be decided over one week in March. As it is, it's going to be a long 3 weeks before the return game is played, and something needs to be done about it imo.
