I wouldn't be surprised if Real Madrid goes far in the Champions League or even win it. I won't be surprised at all because the team has done this over and over again. They work more or better under pressure. When people think the team isn't doing well, all of a sudden they will just pull out one stunt to keep their critics' at bay.
Real Madrid is too tough in the Champions League, they can't be denied that they can perform better when they need a win to advance to the next round. This season is also the same, they are very strong and I don't think anyone who is against them will be confident when facing Real Madrid.
But in general, there is always a surprise that is what makes bettors get high odds. But the fact is that Real Madrid is very focused when playing in the Champions League, especially they have to go through the play-off round, of course they will focus all their strength to win it. Ancelotti is not worried about the opponents they will face, they will try that's what he said while convincing their performance will be better if everyone works together.
