GARY 'Spike' O'Sullivan has no issue with being the underdog against Brazil's WBO World light-middleweight champion Patrick Teixeira.
Both men are being lined up to meet later this year, and O'Sullivan reckons that the Sao Paulo southpaw is very beatable.
O'Sullivan, who is trained and managed by Paschal Collins, and Teixeira are both promoted by Golden Boy Promotions.
"I haven't been in contact with Golden Boy myself, but Paschal Collins has been in touch with Ken Casey (promoter) and Golden Boy. I think it would be a great fight, O'Sullivan who indicated that he might have a warm-up bout before meeting the Brazilian.
"I've always been confident going into every fight, but it hasn't always worked out as you know. It will be no different this time, and I've never lost at light-middleweight.
"I suppose it is the first time in a Championship fight that I'll be fighting a fella my own size. It makes a difference. All the other fights have been against guys that have been bigger than me and heavier."
Twenty-nine-year-old Teixeria has an impressive record of 31 wins from 32 from outings, but his only defeat was an early stoppage to Curtis Stevens in Las Vegas in 2016.
"He got knocked out by Stevens, and I think I'm like Stevens in height and style. He got knocked out in the second round by Stevens, and I think it could be the same outcome, hopefully, for me," added O'Sullivan.
O'Sullivan and Teixeira have also been involved in a social media back and forth with the Brazilian retorting that he would like to end the Leesider's career.
"I said I would be confident of beating him, and he took it very hard altogether. We had a social media spat. I did an interview with Golden Boy Promotions, and I said that I'm looking for a fight with the world champion at light-middle.
"He took fierce offence, and he made up a few photoshop pictures of him carrying me as a baby. Another thing he said is he can't wait to smash my face. I don't take any of this personally; maybe he's taking it personally.
"It does motivate me a bit. I think he's taking it very seriously. He said he wanted to hurt me and end my career. I don't like that kind of talk. I've never talked that kind of talk.
"He's the world champion, and he's six years younger than me as well so I would be the underdog. I was the underdog in the majority of fights I've been involved in. It never worried me.
"I have no issue with being the underdog. It motivates me and takes the pressure off a bit because you're not expected to win."
