#3 Brock Lesnar vs Shinsuke Nakamura (Heel)
Brock vs Nakamura is a match which is most unlikely to happen in WWE. Given Brock's contract with WWE, it is hard to expect him to turn up and have a match which may not be a big money draw for him. Nakamura, on the other hand, has fallen down the pecking order on the main roster and his best days might be behind him.
But that doesn't take away the fact that if these two were to collide, it would have been a titanic encounter. Both these former IWGP Heavyweight Champions are stiff workers and Nakamura would have been a very worthy opponent for Brock given his Japanese strong style of wrestling. Back then, he was a crowd favourite going into the match, and Lesnar, as always, only meant business.
The last time they faced off was at the Tokyo Dome in 2006, where both were competing for NJPW's top prize, the IWGP Heavyweight Championship. Although that encounter wasn't the best these to men could have had, it would have been interesting to see Lesnar and Nakamura square off one last time before both raise the curtain on their careers.
