Maybe he still hasn't seen how Real Madrid's attack is in the Champions League which has even been proven with the 15 trophies that Real Madrid has won. I also quite agree with what you said because Atletico Madrid sometimes makes their defense more solid, but it will not be impossible for Real Madrid's attackers to break down when they face each other in the Champions League. So in this case I am also still more confident in Real Madrid in terms of winning the match than Atletico Madrid even though Atletico is in their best condition this season.
The 15 trophies won by Real Madrid prove that they are the most successful team in this competition, but it should be underlined that each trophy was not won every consecutive season, meaning that Madrid can still be defeated because they have also failed before. This season Real Madrid experienced a slight decline in performance, the proof is they had to fight to qualify for the last 16 through the play-off round. Luckily for them because Man City is also in the worst period during Guardiola tenure as coach.
After the first leg is over, it can be predicted who has the greatest chance of qualifying for the quarter-finals.
