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?
A bull of a player with an eye for goal, good cover for Joao, if we are not looking at him we should be. No fee, would probably only command a sensible wage. Could give another dimension to our game aswell. If we brought him on late on with Joao and Meite. We could just squeeze there defenders into the goal.
