It doesn't work like that; you always need luck. Let’s look at the Champions League campaign Real Madrid won in 2022.
Round of 16: PSG vs. Real Madrid (First leg: 22 shots to 3; the match ended 1-0, with PSG even missing a penalty through Messi. In the return leg, PSG won 0-1, but Real scored three goals in the final 25 minutes).
Quarter-finals: Chelsea vs. Real Madrid (Chelsea faced a mountain of problems sanctions, travel issues, etc. due to owner Roman Abramovich’s Russian ties and the war in Ukraine. Real won 3-1 in a balanced match. In Madrid, Chelsea dominated for 75 minutes and went 0-3 up. They scored a fourth goal making it 0-4 but it was disallowed for a dubious handball. A minute later, Madrid pulled one back to make it 3-1. Then, in the 96th minute, they scored to make it 3-2 and seal qualification).
