Holly Holm remains one of the most interesting fighters in all of MMA currently fighting outside of the UFC's ranks. The former boxing champion is seen by some as a significant challenge for Ronda Rousey and by others as simply a fantastic fighter who would put on a good show against pretty much all members of the women's bantamweight division.
UFC president Dana White swung from calling Holm the "female Conor McGregor," because so many fans were asking him to sign her to announcing that he was no longer interested after a round of negotiations with her management.
Mike Winkeljohn, Holm's trainer, told Submission Radio that the UFC is their desired landing spot, but that the World Series of Fighting has offered more money (transcription via Bleacher Report)
"The UFC is where we wanna be and the numbers have come up behind the scenes, there's no doubt about it ... We’re trying to work something out right now and I definitely see Holly signing with the UFC. World Series of Fighting has offered her more money. A lot of people have started to offer her more money, that I'll let her manager talk about. All the numbers have, basically a little bidding war has begun and we're quite excited about it, but we, we want the UFC.“
Winkeljohn also said that he thinks Holm needs a few more fights to prepare for any potential bout with Rousey.
