Tom Brady secured his seventh Super Bowl ring, extending his record, as the Tampa Bay Buccaneers beat defending-champion Kansas City Chiefs 31-9.
Despite facing Kansas City and their dynamic young quarterback Patrick Mahomes, who came in as favourites, Brady threw three touchdown passes to prevent the Chiefs becoming the first back-to-back NFL champions since Brady and the Patriots in the 2004 season.
Brady capped a near-perfect half of football with a third scoring strike to Antonio Brown to see the Bucs up 21-6, while Leonard Fournette became the fourth Tampa Bay player not on their roster 12 months ago to find the endzone when he broke free for a 27-yard TD in the third quarter.
Brady, who completed 21 of 29 throws for 201 and three touchdowns, was named Super Bowl MVP for a record-breaking fifth time.
At 43, Brady became the oldest player to play in the biggest game in US sport, extending his record for Super Bowl appearances to 10 and joining Peyton Manning as the only quarterbacks to win Super Bowls with two different teams.
Already widely considered the greatest NFL player of all time, Brady made the decision to leave the New England Patriots in the off-season for a new challenge and moved to Tampa Bay, whose only previous Super Bowl win came in the 2002 season.
While at New England, Brady formed the NFL's most successful quarterback-coach partnership with Bill Belichick, and when he left, some felt that Belichick deserved more of the credit, that Brady would get 'found out' without him.
But the Patriots endured their first losing season since 2000 - the year before Brady became their starting quarterback.
Meanwhile, Mahomes completed only 53 per cent of his passes - 26 of 49 for 270 yards - throwing two interceptions in the second half as he got increasingly desperate. The loss is Mahomes' first by two scores in his 54 career starts in the NFL.
After leading Kansas City to their first Super Bowl win in 50 years, Mahomes was rewarded with a 10-year contract last July, making him the "first half-billion dollar player in sports history".
He had become the youngest player to win the Super Bowl and the NFL MVP award, and the 25-year-old is the most exciting talent of a new era of athletic quarterbacks.
