Inter have not been tested yet at all, no domestic challenge, and they finished behind Sociadad in a weak group. Atletico were crap in the first leg, but I expect this game to be better. Juventus always lost to second tier teams after we became accustomed to beating bums in Serie A. I think Inter will get a reality check soon enough, perhaps not tonight, but in the next round for sure. To be a top tier club you need to consistently make it to the later stages of CL. That said, Marotta and Inzaghi have a very capable team now.
