"He will be ideal for City, especially alongside Carlos Tevez," said the former England boss in the Daily Mirror. "That will be a very potent partnership, very strong.
"I wish him well and hope he fulfils his dream and potential there.
"He is a very, very good player and that is reflected in the price.
"He is a big lad, strong and quick too. He also has good technique.
"But most importantly he is a goalscorer who gets them with his left foot, his right foot, his head. That is what City are getting. He is a good buy for them."
