Unexpected results occurred in both matches, Bayern Munich who were believed to be able to beat Barcelona ended up losing points, on the other hand Borussia Dortmund who already had a safe position at the end of the first half had to be embarrassed in the second half by Real Madrid. Outside of UCL, I think the Real Madrid - Barcelona meeting is really anticipated, because both teams come with confidence.
These two matches are very surprising to many people, for me, especially Madrid, because Dortmund is superior first 2-0 and then replied with a score of 5-2, and that is a very epic match for me, with circumstances like Real Madrid should be able to lose even I turned off my TV to stop watching, but a few minutes later the year on my cellphone showed that Real Madrid dominated the match very crazy.
Regarding Barcelona, it was a very interesting match because before Barcelona experienced more defeat than Bayern Munich than H2H data.
