The main thing that can be said in this situation is that this is happening now. Therefore, it is not necessary to extrapolate the situation that is developing at this moment in time for the future. Atletico Madrid should not endlessly lose and this unfortunate series should come to an end. Ronaldo can continue to score as much as he likes in matches against Atletico Madrid, but it is not a fact that this will be enough for an overall victory at the end of two matches. Even if we take into account the current situation, we need to remember that the Champions League is a completely separate story with its own separate motivation on the part of the clubs, because I know a lot of examples of cup tournaments when the club was unsuccessful in the domestic championship and fine in the international arena and vice versa.
I agree, if there is no link between statistics in the domestic league with UCL. sometimes in UCL the underdog team can actually beat wich the favorite one, because I believe every match has its own motivation especially in UCL. and also the Champions League Final Stage will continues in February 2022 so there still a chance for each team to improve themselves in the domestic league and prepare for the UCL.
