Howe's side wrapped up their first signing of the summer on Wednesday by bringing in Elliott Ward, but the manager said that other signings will only follow if they are up to the required standard.
"We need quality additions and I don't think we need quantity," How told the Daily Echo.
"Whichever player we sign, we are trying to make sure they are going to improve the team and the squad so there will not be a huge number coming in. Hopefully, there will be more quality additions in the calibre of Elliott.
"I wouldn't want to bring in someone who was potentially not better than what we have already because you are just adding numbers to the group."
