For me, every team at this stage stands the same chance of winning or getting similar results. Both Chelsea and Real bettis are similarly on the same page at the moment so it would be left for both teams to settle their scores by going all the way to winning the trophy, the only team I wouldn't consider as a candidate for this tournament is Fiorentina, I don't think they have what it takes and I don't expect them to go beyond this level of the competition.
For me, the final match will be between Betis Sevilla and Chelsea. The other teams are not strong enough to compete and Betis and Chelsea are both very strong. At the moment I even see Betis Sevilla as slightly stronger than Chelsea, but in the end it will depend on the form of the players on the day as to who will win.
