City go to Germany holding a one goal lead.
"I've not said anything special. We're not going to do anything special," Guardiola said. "Each one has to try to be a leader on the pitch. The guy who feels comfortable during the game takes more responsibility to be more involved.
"The guys who are more nervous: do your job, play simple, be calm. Maybe five minutes later you'll be ready to do a good performance.
"They are human beings. People forget about that. Human beings have feelings. We know what we have to do. Do what we've done all season. If we win, we have to deserve it – we have to go for it.
"That is going to happen. We've done it an effective way. Of course you have to control your emotions but sometimes you need emotion to win this type of game."
