"We're in negotiations with everyone else - and with some of them, we have been in talks for many weeks," said Cardiff boss Dave Jones.
"My priority was to get players in then chip away at the others."
Jones was hindered by a transfer embargo imposed on the Championship club for the best part of the summer because of a delay in paying debts, including £1.3m owed to HM Revenue and Customs.
But once that sanction was lifted, last season's defeated Championship play-off finalists signed Craig Bellamy, Jason Koumas, Seyi Olofinjana and Andy Keogh on season-long loan deals.
Now Jones is concentrating on securing the Cardiff players he wants to keep.
The experienced manager is taking a more hands-on role in contract negotiations with new chief executive Gethin Jenkins after the departure of former chairman and chief executive Peter Ridsdale left in the summer.
"It hasn't been easy since the change as I have been more involved in negotiations with Gethin," said Jones.
