There's some discussion ... back in this thread about what will happen to Carrington:
http://forums.bluemoon-mcfc.co.uk/viewtopic.php?f=1&t=244975&p=6722949. No one seems absolutely sure about the position in terms of whether we lease or own it, and if we lease it, who the landlord is. However, I do know that City have been telling supporters' club meetings and the like that we'll move out of Carrington completely when the new facility opens.
Though the Academy will be leaving Platt Lane, the fact that we spent 80 years with our home ground a stone's throw away means that the club is keen to keep some kind of base there. I believe it's likely to be some kind of City in the Community outpost to serve the Moss Side area.
