Major match involving former world champion could have happened at AEW All In - Reports

AEW All In is right around the corner, and discourse surrounding the booking of the event has been heated online. According to Dave Meltzer, a highly-anticipated match between two former world champions could have taken place at Wembley Stadium.

The stars in question are AEW's Kenny Omega and NJPW's Will Ospreay. The two have clashed twice already this year, both times for the IWGP United States Championship that Ospreay currently holds. Omega defeated his rival in a brutal bout at NJPW Wrestle Kingdom 17 on January 4, but The Aerial Assassin got his win back – and the title – at AEW x NJPW: Forbidden Door on June 25.

Fans were excited to see the two blow off their feud in a massive third encounter, and Wembley Stadium in Ospreay's hometown of London seemed to be the perfect stage for it.

However, AEW recently put an end to the hype with the announcements that Ospreay will face Chris Jericho while Omega teams with Hangman Page and Kota Ibushi against Bullet Club Gold (Juice Robinson & Jay White) and Konosuke Takeshita.

When a fan on Twitter pointed out that Omega vs. Ospreay is an NJPW feud and couldn't have been done at AEW All In due to politics between the two promotions, The Wrestling Observer's Dave Meltzer pointed out that it actually could have taken place.

"They could have done it at All In if they wanted," Meltzer tweeted.

Now that it's been confirmed that the two won't be facing off in London next weekend, fans speculate that Kenny Omega and Will Ospreay could cap off their acclaimed trilogy at next year's Wrestle Kingdom event.
