Gary "Spike" O'Sullivan (30-3, 21 KOs) believes that a knockout is certainly necessary to come away with a victory when he faces Mexican star Jaime Munguia (34-0, 27 KOs).

Their twelve round middleweight fight takes place on Saturday, Jan. 11 at The Alamodome in San Antonio, TX and will be streamed live exclusively on DAZN.

Munguia was the WBO's junior middleweight champion and made a decision to move up in weight after struggling to make the division limit of 154-pounds.

Munguia won a very close decision over Dennis Hogan in April of 2019. It was the closest that he'd come to an actual defeat, with one judge scoring a draw and another give him the win by two points.

Prior to that bout, Munguia had either stopped or dominated his opponents.

Because many observers felt that Hogan had done enough to win, and Munguia is being pushed as the next Mexican superstar, O'Sullivan is focused on ending the contest inside the distance.

“Unquestionably, I need a knockout. He is a Mexican and a super star,” O'Sullivan said to Seán McGoldrick in the Independent.

“I think if I knock him down in every round but he is able to continue I won’t get the decision. There won’t be many there shouting for me, though I expect I will have a few supporters in the sell-out crowd. Brian O’Connor, whose father Dave has sponsored my suits since 2008, lives out there and he is organising a bus for fans.

“To be honest I wasn’t expecting the fight at all. When I got the call to fight Munguia initially I thought it was for his light middleweight world title. Then I was told he was moving up to middleweight. I did campaign at middleweight for a long time and I believe that this is a fight that I can win.”
