Think the reason he hasn't signed for Palace for another year yet is because he has been commuting from the Midlands and staying in hotels and he is reluctant to relocate his family. That being the case, I doubt he's going to consider coming to the South Coast for a one year swansong. I'd imagine if he doesn't continue at Palace, he will retire.
nothing to do with where you are its the league you are in-he clearly wants to finish at the highest level
