Rejuvenated Arsenal are unlikely to offer any respite from their slide down the table - the Canaries are only four points above relegation - but Johnson is hopeful they can repeat the heroics they produced against the Gunners in October when they triumphed 1-0 at Carrow Road.
"No one expects us to go to clubs like Arsenal and Man Utd and win, but we've beaten both of them at home already this season so who says we can't do it away from home?" he said.
"We know it will be a hard game. If we get anything out of it, it will be a bonus.
"We work hard for each other and we got into Arsenal's faces at home. We upset their rhythm.
"We know it will be tough at the Emirates because they're on a good run of form, but if we go there and play like we did at Carrow Road, why can't we get a result there?"
