A Best of Seven Series between Cesaro and Sheamus to determine which Superstar is physically dominant — and, perhaps, worthy of championship consideration — gets underway this Sunday on the SummerSlam Kickoff.

If the series’ opener is anything like The Swiss Superman and The Celtic Warrior’s last two outings on Raw, the WWE Universe is in for a gloriously unpretentious knock-down, drag-out fight in Brooklyn, N.Y.

Cesaro holds the edge over Sheamus heading into the series, having defeated the former WWE World Champion in close-fought matches on Aug. 1 and 8. The Celtic Warrior contends the losses, the second of which ended via a quick roll-up by Cesaro, were flukes. Bitter over the outcome, Sheamus cost Cesaro dearly later that night, interfering in the Swiss Superstar’s U.S. Championship Match against Rusev.

The hostility continued the following week, with the two Superstars brawling again at the conclusion of Sheamus’ match against Sami Zayn. Seeking to control the chaos, as well as reach a definitive answer as to which athlete deserves to move up the ranks, Raw General Manager Mick Foley then set in motion the Best of Seven Series.

Sheamus will not only be packing a bad attitude this Sunday, but also his typically barbaric sense of competition. With an unrelenting attack and a Brogue Kick powerful enough to detach heads from shoulders, the 6-foot-4, 267-pound Irishman is intent on setting a vicious tone for the Best of Seven Series.

His cool-under-pressure opponent is equally capable of jacking jaws, using a breathtaking variety of European uppercuts to his advantage. And though The Swiss Superman sacrifices some size to Sheamus, he seems to possess the raw strength to toss around anyone smaller than a Volkswagen.

Who will be victorious in the crucially important first match of the Best of Seven Series? Tune in to the special two-hour SummerSlam Kickoff, airing on the award-winning WWE Network this Sunday at 5 p.m. ET/2 p.m. PT. In addition to WWE Network, the Kickoff streams live on WWE.com, the WWE App, YouTube, Facebook, Twitter, Pinterest and Google+.
