Gary Rowett has told four Stoke players, including record signing Giannelli Imbula and Charlie Adam, they are free to leave the Championship club.

Imbula, the £18.3m recruit from Porto, and former Scotland international Adam, plus Maxim Choupo-Moting and Geoff Cameron, are all surplus to requirements and available before this month's EFL deadline.

Rowett is keen to trim his squad before the cut-off point of August 31 and has informed the quartet they have no future at the bet365 Stadium.

It is understood Imbula and Choupo-Moting are even training with Stoke's under-23's, away from the first-team.

Adam, a £4m signing from Liverpool in August 2012, and USA international Cameron have not been included in Rowett's 18-man squads for the opening two games. Adam's former club, Rangers, did show interest in signing the midfielder earlier this summer but a move there now appears remote. Rayo Vallecano and Werder Bremen are understood to be interested in signing Cameron.
