When everything is decided in one match, then perhaps you are right when you say that the teams have equal chances. If they were able to reach the finals, then they are strong enough to do it. The recent match when City failed to achieve victory in the final is an example of how a clear favorite can lose, a few good attacks, some kind of mistake, a good defensive game, and the outcome becomes completely unexpected.
The defeats of Manchester City in the FA Cup and Leverkusen in the Europa League are proof that strong teams cannot necessarily win the title, the same story might happen to Real Madrid if Dortmund plays like Manchester United and Atalanta, which tightly closes all the space owned by opposing players. Dortmund has the quality to make it difficult for Real Madrid in this final, they managed to get rid of PSG by taking advantage of every opportunity they had, their defense was also very tight which made it difficult for PSG players to score goals.
Defensive play and occasional counter attacks are quite effective in making it difficult for opposing players, Ancelotti must have a backup strategy to overcome the defensive game that Edin Terzic might implement.
