Among the names rumoured to show up at Hell in a Cell to accept John Cena's United States Championship Open Challenge were Daniel Bryan, Finn Balor, Dolph Ziggler, and Tyler Breeze, but it's fair to say that no one expected Alberto Del Rio to make his return. There had been rumblings that the WWE were courting the unfairly fired former WWE Champion as part of their search for a top Hispanic talent, but Mexico's greatest export arriving in Los Angeles after being introduced by Zeb Colter still stands out as one of the year's biggest shocks. After cleanly defeating John Cena and becoming the new United States Champion, things are looking good for both the WWE and Del Rio; they have their Hispanic star and Del Rio is arguably back where he belongs after having some well publicised issues with the independent circuit. However, it's impossible not to wonder what's next for Del Rio now that he's holding this title. In the time he's been away from the company, the landscape of the WWE has shifted dramatically, with several new talents being brought up from NXT and the status of various Superstars who may have been on top or at the bottom when he was last around inevitably changing. Who then should challenge the United States Champion for his newly won title? Here, you'll find the ten WWE Superstars who are most deserving of that opportunity and generally just great choices to step into the squared circle with the returning Del Rio. Whether it's down to the no doubt amazing matches they'd have or the opportunity for WWE Creative to come up with something special, all of these are essential opponents...
