The Canaries are safe from relegation but Hughton is already busy preparing for next season.
He said: "We will be trying hard to improve the squad over the summer but it won't be easy. Nineteen other teams will be doing the same so there will be a lot of competition for players.
"Defensively we have held our own but we obviously need to get more goals from the team.
"We drew too many games this season and we have got to start turning more of those draws into wins."
