Eli Manning has said that the New York Giants know the Dallas Cowboys' defensive players "pretty well".
The Giants will face their NFC East rivals in their opening game of the season tomorrow.
The quarterback told the team's website: "I think when you're playing Dallas, you know the personnel pretty well. You've played the same guys the last couple of years so you know the personnel well.
"You're just looking at scheme and most of the preparation is how do they play their zone, what do they do on third down, what do they do in the red zone.
"You're looking at technique, schemes, what plays, how they're going to turn out, how they're going to work and whether they're going to be good concepts for you that week."
The two sides each claimed one victory from their two meetings last season.
