"I'm very happy with his performance. He has experience, he has quality, he has the capacity," Emery told a news conference.
"For Saturday, the decision is easy. Petr can cukspoontinue to start, I believe in him. But if Bernd starts, I believe in him also... they are two goalkeepers who are important for us."
Emery suggested that he would persist with his style despite being outplayed by City and sought a strong response from his players.
"We need to keep our personality, our mentality. Against City, the team kept their ideas, kept their spirit in the game for the full 90 minutes even when we were losing," Emery added.
"That was a good thing... I want us to continue with this work and to be competitive for 90 minutes, but with a better performance both individually and collectively."
Stephan Lichtsteiner or Nacho Monreal will fill in for Ainsley Maitland-Niles, who is out until October after suffering a leg fracture against City. Regular left back Sead Kolasinac is also out for a similar period with a knee injury.
