"I'm hoping to be able to resolve one or two (contract issues) by the middle of next week," O'Neill told the Birmingham Mail.
"There's Olof, Luke Moore and Thomas Sorensen's position. All the people who have a year left to run on their contracts.
"I hate to put a time limit on these things, but by the end of next week I would hope to have certain things resolved.
"I would like to have those done and I think the players would like to know by transfer-deadline day as well. So I'll make decisions on all of them."
