this may be deliberate by the Blues
maybe they dont want to let Walker go so they are creating this perception that they are doing their best to trade him, however in reality they are making it impossible for him to get to another club
It may well be but if he's that unhappy that he's shopped himself around to 3 clubs to try to get out of there I'm sure he'll be thrilled to have to stay another year. He may well walk for nothing next year.
