Well I don't think so IMO, Madrid has been qualifying to play in UCL for so many years ,they played with alot of teams so that strategy thing is out for me....they wouldn't have made it through to last year's final if not for some overlooked mistakes by opponent and this is mostly die minute win though Madrid has a strategy of playing fast pressing games in their last minutes but I think those stuffs that happened last year won't repeat itself especially Bayern, Bayern could have reached the finals if not for the last minute subs . Thus saying Realmadrid won't have difficulty issue in UCL with their current squad doesn't seem right to me.
I do not think Real Madrid will have easy time in Champions League with their current team.
They have history of doing well in tournament but last year they got lucky because of mistakes made by other teams. They also won some games at very last minute. Other teams like Bayern Munich could have won if they made different decisions. This means Real Madrid did not just win because they were best but also because of things outside of their control. So I think they will face problems in Champions League with their current team.
Somehow I don't agree with your opinion about Real Madrid, as if saying that Real Madrid was lucky because their opponent made a mistake even though this club is the number 1 club in the Champions League so Real Madrid's success in winning the title last season was not just luck but thanks to Carlo Anceloti's intelligence in creating a strategy he put Juselu in the final minutes and finally this player was able to break through Bayern Munich's defense and win the semifinal match and finally advance to the final so we can't say it was just luck because Real Madrid is still a strong candidate in the Champions League.
Competing in the Champions League is not easy but I still believe in Real Madrid's ability with the current squad. I don't underestimate other clubs. Bayern or Man City also have the same chance because they are also strong candidates in the UCL.
