10. Rusev Beats John Cena
There's been a lot of talk about the WWE wanting to legitimise their midcard titles, and whether you like him or not, putting the United States Championship on John Cena would at the very least be a step in the right direction. However, it's also the predictable thing to do, and having Rusev this time cleanly beat Cena would keep his undefeated streak in tact and also genuinely shock those expecting the leader of the Cenation to overcome the odds. The Bulgarian Brute emerging victorious over Cena on the grandest stage of them all could help to instantly transform him into a main event Superstar. Whether the WWE will want to make their prized hog look weak is debatable, but a bet on Rusev should be a smart choice to make some cash. He's currently the outsider, and a £10 stake on Rusev will give you a return of £37.50 with odds of 11/4. Cena meanwhile is currently at 2/9 (a £2.22 return).
