Joseph Parker has arrived in the UK ahead of his heavyweight unification showdown against Anthony Joshua.

The WBO champion touched down in London on Saturday, two weeks out from his Cardiff clash with Britain's WBA and IBF champion on March 31.

Parker, unbeaten in 24 professional fights, has been training in Las Vegas alongside trainer Kevin Barry. Having now landed in the capital, the New Zealand fighter will go through his final preparations ahead of the Principality Stadium showdown.

The 26-year-old is the heavy underdog for the unification bout. But Parker is ready to shock the world and end AJ's own unbeaten run.

'It's great to be here. We love it here. It's always felt real but now the countdown begins,' Parker told Sky Sports.

'We've arrived here in good condition; mentally and physically we're strong and we're looking forward to putting on a great display.

'I'm young, fast, strong, my movement is good, I have a great team behind me, and I have my two nations behind me.

'Last year wasn't the best year for us and [there are] many reasons why it wasn't my best performances in the ring but I can tell you this: we're going to put on the best performance of our lives come March 31.'

After WBC king Deontay Wilder impressively stopped Luis Ortiz to retain his crown earlier this month, the stakes have been upped with the winner of Joshua-Parker set to get a crack at the hard-hitting American and a chance to unify all the heavyweight belts afterwards.

Parker is fully aware of the opportunity on offer but insisted he is not looking past Joshua.

'No, we haven't planned anything yet,' Parker said. 'All our eyes are focused on Anthony Joshua; all these other heavyweights can talk to us after this fight.'
