WWE SummerSlam 2021: Roman Reigns vs. John Cena: The Big Fight Preview - everything you need to know

It's time for the Head of the Table and 16-time world champion to find out who the man is.

Universal Champion Roman Reigns clashes with John Cena to headline WWE SummerSlam 2021 on Saturday night from Las Vegas and live on pay-per-view.

The beef has been brewing between Reigns and Cena for quite some time now, with the champion rescinding the latter's offer only for Cena to swoop in and sign the contract anyway. Now, the epic showdown between the Big Dog and one of the most dominant Superstars ever will decide the ruler of the ring.

This year's SummerSlam also touts WWE Champion Bobby Lashley against Goldberg, Nikki ASH vs. Charlotte Flair vs. Rhea Ripley in a Triple Threat match for ASH's Raw Women's title and SmackDown Women's Champion Bianca Belair against Sasha Banks in an encore rematch of their WrestleMania 37 title match.
