Stoke remain coy on the future of their loan players.
Bojan, Joselu and Philipp Wollscheid all spent time away from bet365 stadium last season.
"It's very early days and there's nothing been agreed or cemented with any of those players," Scholes told The Sentinel.
"Technically speaking, until the 30th of June they are still on loan to their respective clubs.
"We keep in touch with all of them, but you are talking about three different individuals with three different positions."
