Paul Lambert maintains none of his summer transfer targets should expect to be in for an easy ride at "little old Norwich" if they join the battle to stay in the Barclays Premier League next season.
The Canaries boss - who oversaw successive promotions - has wasted no time in beginning his recruitment drive, bringing in strikers James Vaughan and Steve Morison. Leeds midfielder Bradley Johnson is another said to be on the verge of a switch to Carrow Road, along with Brighton winger Elliott Bennett.
However, Lambert warned anyone who thinks they can get away without putting a shift in at the Norfolk club will be set for a rude awakening, telling the Eastern Daily Press: "I don't want people coming here thinking it is little old Norwich and it is a lovely place to live, great area - that is not what I am looking for. You want people here who want to achieve something."
He added: "Players that are hungry don't need to be 21 or 22. You can get a lad of 30 who is hungry, a lad at 31 who is hungry, and who wants to do well.
"If I think it is right then I will look at them - if you get experienced lads who want to keep doing well."
Lambert added: "You can take Roy Keane for instance. No matter if Roy Keane was on X amount of money when he started out or what he was on at Manchester United, you would still get the same performances. He was an absolute top, top pro - that is the difference."
Norwich have not been in the Premier League since they went straight down under Nigel Worthington in 2004/05, which was followed by relegation to the third tier of English football just two years ago.
Lambert may have performed a minor miracle in his 20 months at the helm, but the former Champions League winner knows the biggest test of all lies ahead when the squad regroup for pre-season training.
"I think they know the magnitude of it, they know what I expect and I have no worries about any of them," said the 41-year-old. "I have no worries they won't come back in good shape. This is too big for us not to be ready.
"It is the best league in the world that you are going to play in, you are up against the best players and if you come back and you are not ready for that then there is only one person to blame. It ain't going to get any bigger than this - we are right in it now, that is the bottom line, there is no room for error."
