New England Patriots quarterback Tom Brady has revealed that he could "never have imagined this career" ahead of his sixth Super Bowl appearance on Sunday.

Brady will set a record for appearances and with a win on Sunday would become just the third quarterback to win a fourth championship ring.

"I never imagined this in my wildest dreams," Brady told NFL Media.

"I loved playing sports growing up, to get a chance to play in the Super Bowl, I never thought I'd get to play in one. So it's pretty unbelievable to play in six. This team has really got to establish its own identity, and we have a great chance to do it on Sunday."

Brady dismissed talk about his future but suggested that he would like to continue to play in the NFL for many more years.
