It will be very tough for us and I think many Juve fans are going to underestimate Dortmund, especially because they are doing bad in Bundesliga. I can't help it but think of a season when Schalke reached semi finals while they were struggling in relegation zone in Germany, until they went out of the European competition officially.
I think we have a good chance to go through but it definitely won't be an easy match for us. I'm not going to be surprised if we go out, though. I'd never pick them and look forward to that one with confidence as they are a team that plays a very dangerous style which imo doesn't suit us well. On the other hand, it's surely going to be a great match to watch imo.
