Atalanta and Manchester United won their respective finals, but they were different games. Maybe we would also be surprised if Dortmund could beat Real Madrid in the Champions League final, but really that is very difficult to hope for. I know Real Madrid even though I am a Barcelona fan, that's why I dare say that Real Madrid will not lose to a team like Dortmund in the Champions League final.
Yes, many people will compare it to previous finals, where many lost unexpectedly but we hope that Real Madrid does not make any mistakes, it is difficult to expect that Real Madrid will lose later, until now we have never had thoughts like this, although there are surprises in football.
To be honest I wouldn't underestimate Dortmund but here I see the whole Real Madrid squad is ready for the final maybe they will win it as the 15x champion Los Blancos will keep.
Although this is my own prediction, but I am sure many people do not doubt Real Madrid even a little in the final.
