As the current crop of players began pre-season training this week, Keane admitted that two potential signings were virtually agreed and was still hoping to add at least two more ahead of the season's kick-off on August 8.
He told the Evening Star: "We've probably been linked with 50 or 60 players over the last few weeks and it would be unfair of me to talk about players until they've signed.
"I hope, in time, to bring in maybe four or five. We are close with two and there will be hopefully be another two or three over the next two weeks.
"The fun and games will start over the next few weeks when managers get back to their clubs and take stock of what they've got. It's quite difficult these days with the transfer fees that are mentioned, but if you want quality you've got to pay for it."
