Now, he is set to fight for the UFC bantamweight championship at UFC 292 in August.Heading into the highly anticipated matchup, Tim Welch, the coach of 'Sugar' has claimed that UFC is hoping to see Aljamain Sterling be dethroned by the No.2-ranked bantamweight.Speaking about Sean O'Malley's upcoming bout against Aljamain Sterling during a recent interview with Ariel Helwani, Tim Welch said:"Yeah. For sure. Having 'Sugar' be the champion - I mean, what other bantamweight in history has just one-punched people and walked off like Mark Hunt?"He continued:"A bantamweight that's a tall, skinny kid with tattoos and curly hair one-punching people and walking off. The UFC knows what they're doing. 'Sugar' is a big superstar and the UFC helped with that so I'm sure the UFC would love to see a KO artist that's as flashy as Sean be the champion."Catch the comments below (3:03:00)
