John Harbaugh wants Haloti Ngata to be a "game-wrecker"

Baltimore Ravens head coach John Harbaugh has admitted that he wants defensive tackle Haloti Ngata to become a "game-wrecker" for his side.

The 29-year-old is a five-time All-Pro but he has struggled to find his form this season as the Ravens have stuttered to 3-5 in their campaign, months removed from their Super Bowl victory.

Harbaugh told reporters: "Every single play you're going to get doubled-teamed as a nose guard, but Haloti can handle it, and he's playing well. And I think Haloti can be even more dominant.

"I would consider him a dominant player. I want him to be a game-wrecker in there every single play."

The Ravens face the Cincinnati Bengals later today.
