The England boss has paid tribute to the Liverpool defender, calling him one of the best right-backs in Europe.
"We haven't got a lot of right-backs, but for me Johnson is one of the best right-backs in the world. This is my opinion," said Capello.
"I really think that. I'm happy with Johnson.
"He's one of the best right-backs in the world. He is, sure, not just coming forward but also his defending."
