Tony Romo has said that he believes the Dallas Cowboys can always win if they are less than two scores behind going into the fourth quarter.

The Cowboys have been level or behind heading into the last 15 minutes in their last six games, and have won five times.

The quarterback told the Dallas Morning News: "Really, it's just we've gotten to a point where we're a mentally tough football team.

"In saying that, I believe when I step on the field in the fourth quarter, if we're within 10 to 14 points, we're going to find a way to win the ballgame.

"That's just our mentality of what our football team believes late in football games."

The Cowboys play the New Orleans Saints on Sunday.
