The Canaries make a start to their competitive season on Saturday when they play Everton at Carrow Road.
Martin has been happy with pre-season preparations and he expects manager Chris Hughton will get the best of the team again this term.
"You never know what to expect at the start of the season, but I am confident," Martin said.
"We have had a good pre-season and have a good squad, the best since I have been at the club and we will go into it with plenty of positivity."
Martin was one of three Norwich players who represented Scotland in Wednesday's 3-2 defeat by England at Wembley, with Steven Whittaker and Robert Snodgrass also in action.
Although the result went against Scotland, Martin admits he enjoyed the occasion.
He added: "It is disappointing (to lose), but it was an amazing game and an amazing experience, with a lot of positives to take."
