"We've reached a stage now where nobody at the club is guaranteed a place week-in, week-out, but I think the players deserve credit for what they've done considering the changes I've made," said Keane.
"But that will certainly stop now. My spending is certainly over in terms of bringing in six or seven players every transfer window.
"I think we've got the nucleus of a decent team now and although some places in the starting line-up are still up for grabs we need to stabilise the club now and I'm happy to do that."
