Asked for his thoughts on a ‘comfortable’ win, Guardiola replied: “It was not comfortable at all. I am emotionally destroyed! I have 10 more years today. It was such a demanding game.
“From the start of the second half, they were better. We could not control them. But we adjusted something and we were better. It is an incredible result. But we have to do something in Munich at a little bit better not to suffer too much. We will try to do it.
“I have been there many times. I know this team is special. To knock out these top teams you need two top games not one.”
He added: “I know exactly what we have to do there. If we do not perform well, they can score one, two or three. I know that and the players know it.
“It is an incredible result but we have to do our game with a huge, huge personality because otherwise, these are top clubs and teams.
“Here, we have our chances, in our stadium, we are something special this season. We have our momentum, we are clinical and have that weapon. But it is the same for Munich.
“I have been there, you have not been there. I have been there for three years. I know what it means for the people, we are going there to score goals and try to win the game. If not, it will be so difficult.”
