David Haye has claimed a second victory in four months since making his comeback thanks to a second-round stoppage of Arnold Gjergjaj at London's O2 Arena on Saturday.
The previously unbeaten Kosovan was knocked down three times by the 35-year-old Brit in front of 15,000 fans - including former Chelsea manager Jose Mourinho - before referee Terry O'Connor waved the fight off.
Haye's next fight in September will be against American veteran Shannon Briggs, who knocked out Argentina's Emilio Zarate on the undercard.
"I felt amazing," said Haye, who now has 28 wins - 26 by knockout - and two defeats from 30 professional contests.
"The fans have come out to see the future of heavyweight boxing. People thought I was the past, but I am still the future.
"Anthony Joshua is a fight I would relish. But next up for me is Shannon Briggs. He came over to England and talked a big game.
"I told him if he came over and beat someone I would fight him in September. Let's go chump, let's go chump."
Haye was out of the sport for three-and-a-half years after undergoing shoulder surgery in 2013 but returned with a first-round knockout of Mark de Mori in January.
