New York Giants' Eli Manning: 'We have to improve quickly'

New York Giants quarterback Eli Manning is adamant that his side have to improve to get their season back on track.

The Giants fell to their second defeat in a row to a divisional opponent as they lost to the Dallas Cowboys 31-21 in their clash at AT&T Stadium.

Tight end Larry Donnell made a crucial error in the fourth quarter which allowed the Cowboys to take an insurmountable lead, and Manning feels that those mistakes need to be eradicated for the club to have success this season.

"We've got to figure out a way to get better," Manning told reporters. "We have to eliminate the mistakes and the little things so we can execute better and find a way to sustain more drives."

The Giants have a 3-4 record after seven matches this season.
