Martin thinks Saturday's defeat was not a true reflection of the talents at Chris Hughton's disposal.
"The real Norwich is what you saw in the last three or four weeks - not what you saw against Liverpool," Martin said.
"We are deflated at the moment, but we have a work ethic in that dressing room that has got us to where we are over the last few years and it remains the same."
Some Norwich fans left after Liverpool's third goal went in even though the match was just 56 minutes old and they also booed their team off at half-time and after the final whistle.
"The fans pay good money and they have been unbelievable for the last few years so if they want to air their views then that's fine," Martin said.
