#1 Daniel Bryan (c) vs. Kevin Owens (WWE Championship Match)

The ongoing heel run of WWE Champion "The New" Daniel Bryan has been quite successful for the WWE. He defeated five other superstars inside Elimination chamber to retain his title and now will defend it against Kofi Kingston a the next pay-per-view Fastlane.
Bryan is rumored to face a returning superstar at this year's WrestleMania instead of anyone from the current roster to bring star power to WrestleMania. There were seven names pitched as possible opponents for Bryan, such as Bray Wyatt, Sami Zayn, Kevin Owens, Kurt Angle, John Cena, Batista, and The Undertaker.
Finally one of the superstars that could have been picked from that list is Kevin Owens who now is heavily rumored to return and face Bryan for the WWE Championship at the Show of Shows. Owens is expected to return next month in action, and there are videos by WWE of Owens hanging out with his family and being more of a "regular guy". This could be leading to this match at Mania.
