Sunderland boss Roy Keane admits he'll be overseeing a mini-clearout when he returns from the club's tour of Ireland.
"I think there'll be one or two going out before the start of the season," he said. "One or two have fallen behind, one or two have expressed to me that they're not happy but that's the way it is. I won't be ringing up any clubs trying to offload any of my players but I'm well aware we have quality players other clubs are going to be interested in. One or two have already rung me over the last few days."
