Bill Belichick: 'Nothing has changed ahead of Super Bowl'

New England Patriots coach Bill Belichick has insisted that his side will simply look to focus on "the key points discussed all week" as they prepare for Sunday's Super Bowl encounter.

The Patriots take on the defending champions Seattle Seahawks at the University of Phoenix Stadium in Arizona, where pre-match talk has been dominated by 'deflategate'.

"Same thing that we talked about all week," said Belichick when questioned about his side's preparations, according to the NFL's official website.

"I don't think there's anything that's happened the last day or two days that will change what we normally do, fundamentally. Just kind of reinforcing some of the key points that we talked about all week."

The Patriots are seeking a fourth Super Bowl crown, with their last victory coming in the 2004 season.
