It must be you! Ellington has moved from Wigan to WBA once...not moved back (bid turned down) http://www.soccerbase.com/players_details.sd?playerid=16401 Roberts gone in the opposite direction once http://www.soccerbase.com/players_details.sd?playerid=11254
So the definition of "forever switching" Is to have moved once with the possibility of moving again? That must mean I am forever moving house!
