Norwich City can remain a tightly knit group whatever changes the summer brings, according to Russell Martin.

The Canaries' squad has overhauled during the last two close seasons, as manager Paul Lambert prepared for a new level of competition on the back of promotions.

And while this time around City will be safely set for the consistency of a second term in the Premier League, that will not necessarily mean any less movement this June and July.

A number of players are waiting to see if their Carrow Road careers will be extended beyond the end of this season and it remains to be seen how Lambert and assistant Ian Culverhouse plan to progress.

City have impressively maintained their team spirit and ethos through three divisions and a host of past changes – as well as the loss of some big characters – over three seasons.

And Martin is confident the Canaries will be able to do so again if needs be.

'It was the same last year – we had big characters in Gilly (Matt Gill) and Tudur (Owain Tudur Jones) who were big for the dressing room, important for the dressing room, and they left and people came in,' said the City full-back.

'Football is a revolving door unfortunately. It's a cruel business sometimes and it's up to the lads to get us safe as quickly as possible and sort stuff out, and hopefully play their part in the plans for next year.

'But I'm sure for them they will know what they want and they want to be here next year. And the gaffer and Cully will know what they want.

'The lads have just got to keep concentrating on playing as they all do and if things change in the summer, unfortunately they change, but that's football.'

The personnel changes, but City's character traits under Lambert have remained rock solid. And that trend has continued with the summer introductions of former Leeds skipper Jonny Howson and young centre-back Ryan Bennett.

'Nothing changes with that,' said Martin. 'I think you have got a strong core of characters that have been here throughout the whole thing and I think the people that come in just add to that. There are no egos and I don't think the dressing room would allow any to be honest, because of the way we are together.

'We've got no superstars. There is not one player you would say is a superstar. We are a team and we are better as a team.

'We are a real unit and we work harder than a lot of teams, which is why we get a lot of success.'

Martin saved special mention for Howson, who enjoyed his first win in a Norwich shirt on his third start for the club, since recovering from the knee injury that ended his time at Elland Road early.

The midfielder picked up the sponsor's man of the match champagne for his efforts in the 2-1 victory over Wolves on Saturday – and Martin expects goals will soon follow.

'He was brilliant; it's tough because he came in injured and it takes a while to get back to fitness, but I thought he was brilliant with the shift he put in,' added Martin.

'Obviously he changed position and I don't think he's played in that diamond yet, but he was fantastic, full of energy and he's very good on the ball, very comfortable, and I think he's got goals in his game as well.'
