Just random speculation but I initially wondered if the loan of Walker could be linked with a possible deal for Armand Gnanduillet the striker who played against us for Blackpool last January. However a quick Google revealed he left Blackpool last summer and he just became a free agent after leaving his Turkish club. Worth a look?

May be too late as Alan Nixon says
ROTHERHAM. Taking an interest in striker Gnanduillet. Back from Turkey. Ex Blackpool.
