Anthony Joshua's upcoming showdown with Kubrat Pulev will be a clash of styles, according to former heavyweight champion Wladimir Klitschko.
Unbeaten WBA, IBF and IBO world heavyweight champion Joshua, 27, will face Bulgarian Pulev at Cardiff's Principality Stadium on October 28.
Pulev, 36, emerged as Joshua's mandatory challenger after Klitschko retired following his memorable defeat to the Briton before a record crowd of 90,000 at Wembley in April.
Klitschko knows both fighters well, having succumbed to Joshua in that classic bout, while he inflicted the only defeat of Pulev's career in November 2014.
Speaking exclusively to Omnisport, the 41-year-old Ukrainian stepped away from picking an overall winner, but said the following regarding the upcoming bout:
"I think they're tough in different ways and I think it's going to be a very interesting match. I think Pulev has more technique than power, whereas Anthony is definitely a powerful guy. So I think it's going to be an interesting fight."
Boasting a flawless 19-0 record, Joshua is set to make his first appearance in the Welsh capital since defeating Dorian Darch at the Motorpoint Arena in 2014.
Pulev has only one loss in 26 fights, his most recent victory coming against American veteran Kevin Johnson in April.
Also on the card, Katie Taylor will fight for her first world title as she meets two-weight world champion Anahi Esther Sanchez for the WBA lightweight crown.
Taylor moved to 6-0 in the paid ranks with a fourth stoppage win in her US debut last time out in New York in July and saw off Nina Meinke in an eliminator for the WBA crown at Wembley Stadium in April as part of the supporting cast to Joshua’s win over Klitschko.
Sanchez collected the vacant strap on Saturday night with a stoppage win over Argentine compatriot Cecila Sofia Mena in Buenos Aires, adding that to the IBF super featherweight crown the 26 year old claimed in 2016 having moved up from featherweight where she held the interim IBF strap – but Taylor is confident she will make her WBA lightweight reign a short one and triumph in Wales.
