The Canaries boss, who has been pleased with the backing he has received from his board, is hopeful of adding to his squad before the transfer window closes at the end of AugustNorwich manager Chris Hughton is still in the market to sign new players before the transfer window closes.
The Canaries have brought in seven players already this summer, including a new forward line of Gary Hooper and Ricky van Wolfswinkel, and midfield duo Nathan Redmond and Leroy Fer.
Norwich start their campaign at home to Everton on Saturday but, with just over two weeks remaining before deadline day, he has insisted the club are still on the lookout for further additions.
"We are still working hard, the same as everybody else," he said at a press conference.
"We would like to finish the window with as strong a squad as possible. We are fortunate that we were able to do some of our work quite early in the window.
"It is difficult and as you get towards the end of the window there are invariably on a lot of occasions some surprises and some players who become available who weren't before and we have to be open for all of that."
The 54-year-old, who guided his side to an 11th-place finish last season, has been pleased with increased financial backing from the Carrow Road board, but insists the club must continue to keep up with their opposition.
He continued: "By the standards of this club over the past few years it [the transfer budget] has vastly improved, but there are quite a few clubs you can look at who have spent considerably more than they would have done in the past."
"If you want to improve and bring in better players of course the prices are escalated at times and at times you have to go to those levels. We have strengthened but so has everybody else.
"Everyone feels they need to get themselves into the best possible position to start this campaign and try and be as strong as they can. We feel we have improved but you have to go and prove that on the football pitch."
