#4. Seth Rollins vs WWE's Swiss Superman Cesaro
Seth Rollins and Cesaro are best friends outside the WWE ring. On screen, the two have put on some of the best matches in recent memory.
Since Rollins made his return to WWE, he has picked a fight with Cesaro. The beef is due to "The Swiss Superman" not liking the new vision that Rollins has for himself and the company.
The Messiah hasn't been able to gain much momentum in his feud with Cesaro. This past week on SmackDown, however, he sent a message when he attacked Cesaro mid-way through the latter's match with Murphy.
It's unclear if the two stars are set to collide at Fastlane next weekend or if WWE is saving the match between them for WrestleMania next month. Currently, there is no update on a potential card for WWE Fastlane.
