Manning has admitted that he is still trying to adjust to the new system after missing the early part of his side's organised team activities after undergoing ankle surgery.
"It's re-energised me," Manning told the New York Daily News. "I'm trying to speed up the process of getting comfortable in the new system. I don't have 10 years. I have a few months."
Manning threw for 3,818 yards in the 2013 season along with 18 touchdowns to 27 interceptions.
