While he has clashed with Capello in the past, it doesn't detract from the fact that he thinks the Italian is the right man to be leading England.
Redknapp told the Sunday Mirror: "If I have an opinion about something I'm not frightened to air it, but it doesn't detract from the fact that I have a great deal of respect for Capello and what he has achieved.
"His record in management is very impressive, and when you combine that with the players he has at his disposal with England, people should be optimistic.
"Naturally I'm very patriotic, but if I didn't genuinely feel we had a chance of success I would say it.
"If I thought the manager and the players weren't good enough I would be the first to say."
