Dolph Ziggler vs. Rusev
Rusev is currently out of action with his leg injury, but he is likely to recover in time for SummerSlam. The injury is actually a blessing for WWE. They now have the opportunity to pit these two up against each other at a big stage like SummerSlam. Lana should be the main factor in this match as well. If WWE wants to take it to the next level, they could make Lana the special guest referee as well.
This adds the possibility of Lana turning into the situation. Although, it would sound like a big mistake, it might help Rusev revive his career. Or WWE could just bury Rusev and give Ziggler the win while Lana flies free for some other feud.
Big Show vs. Ryback vs. Miz (Intercontinental Championship)
The saga of Big Show, Ryback and Miz is nowhere near its end. Like it or not, this angle might run all the way to SummerSlam and beyond. Big Show has failed to evoke emotions among the fans till now and will have to produce something spectacular if he is to have heat in the match. Ryback, on the other hand, should show that he deserves to hold the championship that was once held by legends.
Entertainment quotient in the feud will come from the side of Miz. The Awesome one has no trouble getting the crowd chanting and his chicken antics are funny as well. It is hard to tell who will walk away with the title so early, but Ryback is the favorite here since he has only started his reign.
