McDonnell tackles the Mexican opponent, who holds a 28-fight unbeaten record, with 22 knockouts, for the vacant WBC world super-bantamweight title and is hoping to create British boxing history by joining twin brother Jamie as a world champion.
He tells Approved Garages: “Vargas shouldn’t underestimate me, I have 100% prepared and have what it takes to claim that vacant title. Hasegawa was a good champion but it’s now my time to become the new champion.”
“This is it now," said Doncaster fighter McDonnell, who has won the British title at the Hull venue three years ago.
Approved Garages asked him how his training has been over the past few months – in which he said, “I’ve come on loads since the Sanchez fight – we’ve been working hard daily, and every day we see improvement, we always work hard for every opponent, but this time I’ve been even more focused and pushed a little harder, because I know it’s a big step up and a world title at stake.
Gavin McDonnell’s twin, Jamie, has a status as WBA bantamweight world champion. The charismatic duo from Doncaster, both 30, have each collected a pair of British European titles but at different times.
Gavin tells us, “My brother is always there with me, helping me, giving me pointers as he has been there and done it. I’m looking forward to becoming world champion and standing alongside him, as Britain’s first ever twins to hold world titles at the same time.
"This is huge because I don't know any other twins in the country that have done what we've done, so we’re making a bit of history here as well.”
