Martin, 25, admits there is no way Norwich can give up their attack-minded approach to games.
He said: "You get punished at this level. Robin van Persie is in the form of his life at the moment and he is one of the best players in the world.
"But we move on and learn a lesson from it. We need to defend better. If we get back to a solid base we'll win games.
"It's really tight. Two wins in this league gets you in the top eight, two losses can drop you in the bottom three.
"We're happy with the total we've got — 13 from 12 games — but the next stage of the season starts now."
