Johnson scored in successive victories for the Canaries as they beat Watford and Blackburn Rovers in the space of four days, but he believes that Tettey's willingness to sit back has been a key factor in his attacking contributions.
"It's great to be on the scoresheet again, and I was absolutely delighted with both of the goals," the 27-year-old told reporters. "But having Alex Tettey alongside me in midfield has been a big help because we have a great understanding.
"He gives us the extra defensive security and it means I can get forward much more. He is always telling me to attack more."
Norwich will be back in action against rivals Ipswich Town on Saturday afternoon.
