Super Bowl 55 will take place on Sunday when the Tampa Bay Buccaneers take on the Kansas City Chiefs.
If Brady and the Bucs win, it will mark the first time a team playing in their own stadium will have lifted the Lombardi Trophy.
If Mahomes and the Chiefs win, it will be the first repeat since Brady and the Patriots did it in 2003 and 2004. It's even quite unusual for teams to get to the big game two years in a row.
So who do you think will win?
