Anthony Joshua hit New York vowing to “handle business” in his Wembley Stadium showdown with Wladimir Klitschko.
Joshua will defend his IBF heavyweight title against Klitschko and the pair went head-to-head at Madison Square Garden on Tuesday before facing off again in Times Square, ahead of their record-breaking showdown on April 29, live on Sky Sports Box Office.
Klitschko, who is looking to become a world champion for the third time, admitted that the New York leg proved their showdown is the "biggest stage" of his illustrious career, but Joshua remained calm and focused before firing out a warning.
"I know I'm going to be facing the best Wladimir," he said.
"I think the time is right. It may seem soon to people. This is my gold medal fight once again.
"I'm here for a reason. I'll handle business the way I've always handled it. The goal is the same – to be victorious."
Joshua was in typically calm mood as he made his debut in front of the American media on the back of compatriot James DeGale's world title defence in Brooklyn two weeks ago and Carl Frampton's loss to Leo Santa Cruz in Las Vegas at the weekend.
Klitschko is no stranger to America, having boxed there 12 times in his stellar career that has seen him dominate the division for 11 years.
The Ukrainian will be 41, and will not have boxed since losing his belts to Tyson Fury in November 2015, but made it clear his age will be irrelevant when he walks out at Wembley in front of 90 000 fans.
"Good day New York, I'm still around!" he said.
"This fight is the biggest stage I have ever fought.
"I think it's the perfect time for both of us. In three years he'll be too good and I'll be too old. It's a signature fight for boxing.
"I am obsessed with my goal to become three-time world champion."
