Man City boss Guardiola: In the past Real Madrid would've won 5-1

However, Guardiola knows that his team will have to step up a level to progress to the semi finals.

I had the feeling it is a process. This result in the first seasons together we would lose 4-1, 5-1," he told reporters post-game.

We were not stable emotionally. And being stable emotionally is so important.

We have an idea and we believe now in what we want to do but it is impossible to control all the time against Real Madrid. You have to stick it.

In the first seasons, we would not. Now we are more stable and hopefully in the future we can do better and better."
