Baltimore Ravens coach John Harbaugh has insisted that he believes Denver Broncos quarterback Peyton Manning still has what it takes to produce in the NFL.

Two years ago, Manning dropped seven touchdowns on the Ravens in the season opener, and Harbaugh admits that he still sees the same player today.

"What I see on tape, he's got it all still," he told the Denver Post.

"We are preparing for Peyton Manning, everything he has ever been and what we know he still is. He is a great player."

The 39-year-old is under pressure this season as critics have suggested that he has not looked settled in Gary Kubiak's new offence.
