This match is the most competitive and reputation game, because to win the title in this season will require a lot of hard work and reputation. Real Madrid are currently known as hard-working players here, but you'll notice that Borussia Dortmund have made it to the final because of the hard-working team.
I still can't predict which team will win because the weaker teams are aggressive in the final matches. Because their willpower works solely towards winning, any player is prepared to perform well in order to win. So we have to wait till the end of the game which team will win and touch the title.
This is going to be tough because some of the legend in the both teams will be playing their last match with the team and each will like to make a history, Borussia Dortmund legend Marco Reus announced his departure from the club after staying for twelve good years, and will like like to have a good ending by helping them to win this champions league, although he have good record but to clocked it all with champions league, while Toni Kroos of Real Madrid also announced his retirement from the football and this final will also be his last match and will also like to have the same Marco Reus want for is club that why i said this match it going to be tough.
The both teams have the chances of winning because they are both in a good condition now, but Real Madrid have the higher chances of making it due to the regular participation and it have become part of them, this alone creates fear in the mind of opponent when they are facing Real Madrid in champions league final, they have the experience and currently they are in their best form, but still i can predict this game, let wait for the time and see who comes out champion.
