5. Roman Reigns
They may have crossed paths in tag team matches previously, but if Undertaker had a few more years left in him then a meeting with WWE's new chosen one would be an inevitability. Some fans may groan at the idea, but these are fans who haven't really been paying attention to the development of Roman Reigns. When he is kept away from long monologues on the microphone, Roman Reigns has had a truly stellar year in 2015. His evolution in the ring continues and he is far from the finished product, but he is more than worthy of his spot in the upper echelons of the card. A Roman Reigns vs. Undertaker match would be big money for WWE in the future.

Now living in Prague, John spends most of his time trying to work out how Tomohiro Ishii still stands upright. His favourite wrestler of all time is Dean Malenko, but really it is Repo Man. He is the author of 'An Illustrated History of Slavic Misery', the best book about the Slavic people that you haven't yet read. You can get that and others from www.poshlostbooks.com.
