Hughes has been frustrated in his bid to significantly strengthen for the new campaign, luring only Erik Pieters and Marc Muniesa, as well as Oussama Assaidi on loan from Liverpool, but is confident of progress on the field.
"I've a good group of players, but we do need a little more help in terms of that group and the type of players I want to bring to the club if I can," Hughes said.
"If that's not possible then we'll still have a group that has the capability of doing well in the Premier League again.
"It's going to take some time - it may take more time, may take less than I think - but the intention is to be a successful top-10 Premier League side on a regular basis."
