The Canaries chief admits he would rather focus on his contracted players and not let loan players dominate his squad.
"I felt over the course of the season we probably had too many [loan players] because of the disruption it caused," he told the Eastern Daily Press. "The policy will be to try and get as many contracted players into the club as possible and then we may need to supplement that with a smaller number of loan players maybe for a longer period.
"I think the more successful loans probably do come from the ones that know they are here for the season - although at the same time it is a little bit of a gamble every time you go into that market.
"It is not something we have closed the door on - there probably will be areas in the course of the season which will need to be addressed when maybe contracted players get injured and you have to react to it fairly quickly.
"The main idea at the moment is certainly to get contracted players into the club who will be fighting for their own futures and I feel that's important."
