ONE FC have stormed to prominence in South East Asia, holding events all across the area in just about every territory possible. They boast the top welterweight fighter outside the UFC in Ben Askren, a once-coveted UFC candidate in Bibiano Fernandes, and former UFC names like Brandon Vera. They also have a fair amount of money to offer, and can be seen as beating the UFC to the punch in Asia. If Alberto del Rio wishes to return to MMA and feels comfortable fighting in Asia, ONE FC should definitely be in the picture. There are a few interesting possible matches with names like Vera, though it's likely he would get a couple of lesser known names to start.
