Apart from that, if I consider the odds factor given by the bookies, then Real Madrid still looks to be able to play well in this match. Therefore, it is not surprising that Real Madrid will be able to turn things around but for me personally, I still believe that Barcelona is indeed better at this moment.
Most people must have put a lot of faith in Barcelona, considering that in the first leg they won the game and in the second leg they will play at Camp Nou, so it's natural that many people see a much bigger chance of victory for them. Real Madrid also have a much better chance and Ancelotti can always deal with difficult conditions like this in big games and I'm sure he will surprise us in this game.
I didn't see the chances that the bookies gave to analyze the win in this game, but one thing I saw from Real Madrid always play to win, even though they are under pressure and we have seen so many games for this.
Both teams had chances to qualify, but either way Barcelona had the advantage actually work in their favor. Barcelona just need to avoid defeat to qualify, either they can draw or they also hope to win. I'm not going to put Real Madrid ahead especially because of the second leg at Spotify Camp Nou, they have proven a lot this season especially against La Liga sides including Real Madrid.
Speaking of opportunities no one will doubt Barcelona in the second leg, besides playing at Camp Nou and a 1-0 victory at home to Real Madrid is a good capital for them. But I still doubt Barcelona can play better like the first leg, let's see how the strategy of the two coaches prepares the match and I do not doubt Ancelotti's ability to play a strategy in a crucial match like this.
