I think it will be more interesting if Real Madrid will play against Atletico Madrid. It is because Atletico Madrid knows well Real Madrid. And the match Real Madrid vs Atletico Madrid always becomes a tight match. When Real Madrid vs Leverkusen, I think it will be easier for Real Madrid. Leverkusen attackers look like not really difficult for Real Madrid defense. Leverkusen is only strong in defense, but Xabi often makes a mistake in selecting the players in attacking line. Anyway, as far as I know, it is still not clear that Real Madrid will play against Atletico Madrid or Leverkusen. Have you got an update about the match schedule in UCL?
The meeting of these two teams is clearly much more interesting because Leverkusen is coached by Xabi, who is also a former Madrid player in the past. This can be said to be a harmonious meeting because maybe in the future Xabi will be included as a candidate to replace Ancelotti. Real Madrid will try to show Leverkusen that their experience in the Champions League is an important lesson. Actually, it is very unfortunate if they have to meet earlier, because I want these two teams to continue walking on different sides for a while.
