Russell Martin feels Norwich showed their ambition by refusing to part ways with captain Grant Holt during last month's transfer window.
The Canaries have been one of the surprise packages of the Premier League this season following their promotion last year and currently sit ninth in the table.
Holt's performances have been pivotal to their progress so far, with the striker having already netted nine goals in all competitions for Paul Lambert's men.
The skipper predictably attracted interest in the transfer market last month, culminating in Rangers' unsuccessful deadline day bid.
Defender Martin believes keeping Holt, as well as bringing in his former Peterborough team-mate Ryan Bennett and ex-Leeds captain Jonny Howson, has sent a clear signal to Norwich's rivals that they are serious competitors.
"There was no uncertainty in our group that anyone would go at any point," Martin told The Pink'un.
"When they put in a bid for Holty it was quite late on. It would take a lot of money to let him go from this club.
"When the manager came out and said that no one was going, we knew as players that no one would go. We're lucky the club has stayed strong, the manager has stayed strong and we've shown our ambition.
"It might have been easy to say 'Yes, we'll take some money for one of our players' but not at all. He's been massive for us. He's our captain, he's a big character on and off the pitch and it was a bonus to keep him.
"To be honest, I'm sure there are a few clubs looking at a few of our players because of how well everyone's done and that's the way football is.
"There will always be speculation but we've kept our group and it's a strong group and we've added two more who will definitely be of benefit to the club.
"We're in a stronger position now than we were a week ago, so it's brilliant stuff for the club."
