Conor McGregor was unimpressed by the pay-per-view buyrate for Jake Paul's rematch with Tyron Woodley in December.
The YouTube star viciously knocked out the former UFC welterweight champion in a star-making performance that saw his star rise in the boxing world, but the event itself was reportedly not a box office success.
A number in the region of 65,000 buys was said to be all the bout drew on cable, with Paul denying that figure but admitting it was not his "best business night".
