Oldham boss Ronnie Moore is interested in signing Rotherham's Paul Warne, Rob Scott and Martin McIntosh this summer.
The former Millers manager revealed: "I'll be ringing Mick Harford to have a word maybe later this week.
"Scott and Warne will be out of contract, but I think there's every chance Mick could let them all go.
"He wants a clean sweep to be honest. I've approached two of the players' agents. They're the type of players that could do a job," Moore added.
