For me FC Chelsea was always the favorite in the match up against Borussia Dortmund. I know that many people thought, that Dortmund would be the favorite because they had only wins up to that point in the second part of the season and FC Chelsea was doing not so well at the same time, but if you have looked a little more closely into the performances of Dortmund, then it was pretty obvious, that they had a lot of luck to win all their games back then. They could have easily lost a few of those games or made a draw because they were not the better team all the time.
It also was the same in the first leg against Chelsea where Dortmund only won with 1-0 because they were extremely lucky and Chelsea was not efficient at all with their chances.
This time though i think that Real Madrid is definitely the favorit against Chelsea but the blues definitely also have a chance to advance. For me it is like 60:40 for Real.
If you really watched the match you will understand that Chelsea played a good football but luck was on Dortmund side, when they were able to counter Chelsea and got a goal, during the second leg they came for a draw thereafter Chelsea got a goal, Dortmund players started playing rough football especially Emer Can who was supposed to be booked twice, Chelsea didn't give them a chance until the injury time when Dortmund had most possessions, even at Chelsea worst you won't write them off, the match between Chelsea and Real Madrid is a 50/50 for both side.
At the end of the day Chelsea made the night by winning the game
Dortmund did not do so bad though but Chelsea was the better side
The officials were not partial just as the the media and people talked good thing they helped not to sack Potter
