Terry said: "I am 100% sure that Rio can come back. He has not been fully fit but when he plays he is still one of the best defenders in the world without a doubt.
"He is also still playing for one of the best clubs in the world. It is very much similar to with Frank. When he wasn't selected, people wrote him off and it's the same with Rio.
"But you can never write two world class players off and Rio will be back in an England shirt. I'm sure of that.
"He is a world class player and the players believe in him."
