9. Paul Heyman And Brock Lesnar
WWE.comWho wouldn't want to see this feud? It ties up so many different story arcs and has the ability to lead to the match that everyone is dreaming of. Heyman has shoved the fact down all of the WWE Universe's throats that his client Brock Lesnar conquered The Undertaker's undefeated streak at Wrestlemania XXX, immortalising the duo into the history books. With no timetable for The Undertaker's return, or whether he will even make a comeback, this is a perfect feud for Sting to debut in. There are a few different angles this story could take.The most likely is Sting debuts to feud with Heyman, leading to the returning Brock Lesnar, who dismantles the WCW legend as he did The Undertaker. That in turn could lead to the return of the Deadman, forming an iconic tag team with his legendary counterpart. The possibilities of Sting and Taker tagging together to take down the unstoppable force that Brock Lesnar is historically pleasing and would be a nice way for both men to finish their illustrious careers. That in turn could then set up the long rumoured Sting vs Undertaker WrestleMania 31 match. The problem with WWE booking this feud is that Lesnar has a scheduled match with John Cena this summer. The prospect of Sting vs Lesnar further down the line has certainly got fans excited though.
