It's far better to create many chances and score *only* 4 goals than to be highly efficient and score 4 goals from few chances.
Wierdly, had we been average and scored a late winner, many people would have felt more satisfied. Which doesn't make a lot of sense really. We put in a great performance, given the circumstances (played a lot of time with our 4th-5th choice RB). We played much, much better than vs PSG last season. But we were luckier vs PSG. Hopefully, this time we'll reach the final again and will be luckier/better in the final.
Given that one of the best left forwards in the world was playing against a nearly 37 y.o. midfielder at RB, I'm happy that we won. Real are not likely to beat us by 2 goals in Madrid. If anything, we are likely to win again. Unlike the game at Atletico, which was 3 days after a game vs Liverpool, this time around we'll have 4 full days to recover after Leeds. This can make a lot of difference, we can put in another great performance at Bernabeu.
