Manchester City boss Pep Guardiola insists they have no false sense of invincibility.
Losing to Norwich last week was compounded with a defensive injury crisis as John Stones was ruled out for five weeks, having already lost Aymeric Laporte for six months.
"It's not a problem, it's a challenge," Guardiola said.
"It's your problem when you say we can't lose because we know we can lose.
"Tomorrow we have the feeling we can lose. When we lose one game in the Premier League why should we have doubts?
"I didn't have doubts after one defeat because they have shown many, many times they can do it."
