You can tell Dortmund and Bayern are used to playing quality sides, whilst Barca and Real can auto-pilot win 70% of their matches in La Liga, if not more.
Spot on man!
I think that factor played a major role in both of the games. At least Barca are used to putting away top sides over the years. Madrid on the other hand struggle against top sides outside of Spain. Before Jose arrived, they were knocked out in like 5 consecutive Champs League Round of 16s.
