#1 Brock Lesnar vs Bobby Lashley
It's a match that we've all been waiting to see ever since Bobby Lashley made his return to WWE - and for some reason, it hasn't quite come to fruition just yet.
If they want to make this match as big as it possibly can be, then let's get a UFC vs Bellator superfight going. Both men have enjoyed success in mixed martial arts in their own right, both are capable of telling a great story, and both would probably be up for showing us what they've still got left in the tank.
Brock Lesnar and Bobby Lashley are established enough to know that they wouldn't really be hurt all too much by a loss, and given the fact that they're both heavyweights, you can just about guarantee that we'd see fireworks.
Whether or not WWE would commit to this idea or any of the previous ideas, is a different matter altogether - but sometimes stepping outside of your comfort zone isn't the worst idea in the world.
