Former world champion Amir Khan threw shade at Jeff Horn during the Australian's WBO welterweight world title defense against Gary Corcoran in Brisbane on Wednesday.
Horn won the belt in a controversial unanimous decision victory over Manny Pacquiao in July.
Pacquiao was originally scheduled to fight Khan in April in UAE, but then withdrew after his team claimed there were funding issues with the investoers who promised to financially back the event.
Khan, who owns wins over the likes of Zab Judah, Marcos Maidana and Paulie Malignaggi, had been aiming for a shot at Pacquiao for several years. The last time the Brit stepped into the ring, he move up to catch-weight of 155-pounds and was knocked out cold by then WBC middleweight champion Canelo Alvarez in May of 2016.
Sitting ringside for the scrappy Horn's first title defence, Khan obviously wasn't impressed with what he saw.
"Watching the Horn v Corcoran fight live, Now I know why Manny Pacquiao picked Horn to fight and not me and he still lost," Khan stated.
Khan was part of the "I'm a Celeb" reality show that was being filmed in Australia. After he was eliminated from the show, Khan made a decision remain in the country in order to sit ringside so he could scout Horn.
Horn (18-0-1, 12 KOs) was able to secure an eleventh round stoppage over Concoran, and now likely has to make a mandatory defense against Terence Crawford on an April date in Las Vegas.
But Khan is planning his comeback in the early part of 2018, and he says Horn is at the top of his list of potential targets.
"The welterweight division is definitely a good division for me. I'm more comfortable there, I've been champion in that division, so I want to definitely win a world title in this division again. [Horn] will definitely be on my radar. He's a great champion and he might be a fight that I take in the future," Khan said.
