The UFC is the largest mixed martial arts organization in the world, which means that the majority of the sport's best fighters already compete inside the Octagon.
However, the UFC is still always on the lookout for new fighters to fill the ranks or to help build the recently added flyweight and women's bantamweight divisions.
This is a list comprised of fighters the UFC can actually sign. None of these fighters are currently locked into exclusive deals with other promotions, so guys like Shinya Aoki or Bellator's heavyweight champ, Alexander Volkov, are off the table.
With that in mind, these are the five fighters the UFC needs to sign. They would all be welcome additions to weight classes that are in dire need of fresh and exciting talent.
As is customary with lists like these, there are always fighters who don't make the cut. Please feel free to exhaust the comments section below and include other fighters you think the UFC ought to sign.
