Roy Hodgson insists he has not called time on Ferdinand's international career but many believe recent events have signalled the end.
"It (international retirement) must be on his mind, the way it has been handled and the way everything has gone," he said.
"It was a very delicate subject leading into the European Championships; obviously choices were made so he must feel like retiring.
"Alex Ferguson has already said he should say 'no' (to a recall) any way but whether that's been taken out of his hands now I don't know.
"If I was Rio I don't think I would have the willpower to come back and say 'I want to play for England again'.
"But he plays sometimes as if he is wearing a pair of carpet slippers because he makes it look so easy so if Rio wants to play for England he should still be there."
