Anthony Joshua says he will be studying Deontay Wilder's every move as the WBC heavyweight champion makes his next title defence against Dominic Breazeale this weekend.
Wilder battles Breazeale at the Barclays Center in Brooklyn, New York, in the early hours of Sunday morning, live on Sky Sports, just a fortnight before Joshua's US debut in the same city on June 1, live on Sky Sports Box Office.

Britain's unified champion has been preparing for Andy Ruiz Jr at his training camp in Miami, but Joshua will be keeping a watchful eye as Wilder faces his former opponent Breazeale.
"Yeah, yeah 100 per cent," Joshua told Sky Sports, when asked about watching Wilder.
"Styles make fights, I think Wilder will fare well against Breazeale. I think Wilder is too quick, he's a very, very fast heavyweight, but Breazeale is tough, took me seven rounds.
"I hope Wilder does it in nine, so I can be like 'hey I done it earlier'. You know how it is, comparisons and stuff, but yeah it will be interesting to see.
"You look at the small things, I look at the small details - when he's getting tired, how many right hands he throws in a round. I look at something different, rather than comparisons to the rounds."
Breazeale proved his toughness during a brutal battle with Joshua in June 2016, eventually succumbing to a barrage of punches in the seventh round of their IBF title fight at The O2.
Joshua has voiced his respect for the Californian, who responded with three stoppage wins ahead of his second attempt to become a world champion.
"When I looked at his interview after and I saw his face, I said wow you definitely took a beating, and he stayed in there," said Joshua.
"He got hurt in the second round, stumbled, stayed on his feet. Come game, it's a world championship fight, that's what I'm saying.
"Breazeale at the time, he may not have been Wladimir Klitschko, but he came and put up a fight."
Watch Deontay Wilder's WBC heavyweight title fight against Dominic Breazeale at the Barclays Center in Brooklyn, from 2am on Sunday May 19, live on Sky Sports Action and Sky Sports Main Event.
