A few days ago (before Brock Lesnar announced that he had signed a new contract with the WWE), bookies had Roman Reigns as a firm favourite to win the WWE World Heavyweight Championship at WrestleMania. That's all changed now though, and both men are at 5/6, meaning that a £10 bet on either will earn £18.33. As a result, it's best to place a bet on who you most want to see win this clash between the Beast and former Shield member. Honestly though, with a new contract in hand, Lesnar winning seems like a much safer bet than it did a day or two ago. Rumour has it that Triple H has been pushing Vince McMahon to keep the belt on Lesnar - who will continue to make sporadic appearances - and to have Bryan and Cena win in order to raise the importance of the WWE's midcard titles. All of this points to a victory for Lesnar, so that's probably where your money is best spent.
