Manchester United manager Louis van Gaal has refused to rule out the possibility of signing goalkeeper Victor Valdes.
Manchester City boss Manuel Pellegrini says he is confident that England goalkeeper Joe Hart will sign a new contract.
Barnsley defender Rob Edwards has agreed to a switch to League Two Fleetwood on a month-long loan.
The 29-year-old has yet to feature for Barnsley this season due to a niggling injury and will be looking to gain some match fitness.
Barnsley manager Keith Hill signed Edwards and made him captain but injuries and lack of form restricted the Wales international to just 18 appearances last term.
Edwards has fallen down the pecking order in his absence with Stephen Foster, Jim McNulty, Martin Cranie and Scott Wiseman all vying for the position.
Hill recently allowed another defender, Lee Collins, to join Shrewsbury Town on loan.
