I don't think there is any doubt that stones will not be No.1 choice once he returns.
It's not like Distin has come in and reminded people of the rock he has been in the past...he's looked every bit the aging player!
I would still put money on Distin being number one until he really screws up, despite Stones being far far better than him and Distin costing us pretty much every goal we concede now.
