New England Patriots quarterback Tom Brady has admitted that he and his teammates must be at their best if they are to reach this year's Super Bowl.
The Patriots take on Denver Broncos on Sunday night in the AFC championship game and Brady wants them to learn from their last encounter with their rivals, which ended with a narrow victory.
"I think it's important to see what we did - well, I know what we did," he told the club's official website. "We turned it over three times in the first quarter and we couldn't do anything offensively.
"We were just pretty terrible and they played good. They did some things that challenged us. However the game ebbs and flows, I think we have to be prepared to just play for 60 minutes. You're not going to play 30 minutes against this team and then think you have it all figured out.
"They're going to change, we're going to change. I think that's the thing they're able to do on offense and defense to be able to adjust things."
The Patriots lost at this stage of the playoffs last season to Baltimore Ravens.
