New York Giants quarterback Eli Manning has admitted that his offense must improve in the final pre-season game against the New England Patriots.

So far, the Giants have managed just two touchdowns this month, a statistic Manning will be looking to improve in his limited minutes on Thursday night.

"We have to play better," NFL.com quotes Manning as saying.

"We have to be better in the red zone and convert on third downs, so there's some room for improvement."

Manning threw for 3,948 yards in his 16 starts last season.
