My worry is complacency. The Dortmund game was a perfect example of that. Very good first leg, very bad second leg.
After beating Madrid and Bayern in a week they started having complacency issues.
Yesterday night didn't make an exception, sadly, and could've cost us CdR trophy and it did cost us 30 mins of added playing time with Inter match waiting just around the corner.
Imo it will be quite odd to be complacent vs. Inter at home from the first game. This would pose a problem in the return leg, just like it happend vs. BVB if they manage to secure a confortable win at Montjuic.
I can't imagine them being complacent from the first leg.
