It's not just because of luck that Dortmund and Real Madrid were able to get to the UCL final this season, but indeed both teams have quite good quality and even though there is a little element of luck, it is also combined with the quality that Dortmund and Real Madrid have so they can get to the UCL final. this season, I think it is appropriate and we cannot continue to say what happened in the semifinals is the luck of the two teams so that they can qualify for the final but we have to look at it as a whole.
I agree with you because football is about strategy and there is no way luck will be enough in the final result. Dortmund and Real Madrid were much better prepared to play in the final and both of them did their best to qualify for the final with very satisfying results. Dortmund's task now will be much tougher because they have to face the king of the Champions League and facing pressure in the Champions League will be much different from the domestic league.
Of course luck is the biggest gift they get and that happens because of the hard work they have done so far. The focus is now on the two teams coming out as champions and we want to see how the two teams can play with more pressure in the final match, so that it doesn't get boring when we watch these considerations.
