As reported by The Mirror, Triple H is still hesitant to host a WrestleMania in the UK, primarily because of the misconception that the 1992 SummerSlam was a success.
"The time zones are the big kicker - we have to go where the most people can watch. I always hear about Wembley, I always hear it was such a massive success: It was not. From a business standpoint, it was not. That's why we didn't come back and that's why we're still trying to figure it out."
The 1992 SummerSlam event in London drew ?80,355 fans at Wembley Stadium, and was when The British Bulldog was a huge star. He went on to defeat Bret Hart to win the Intercontinental Championship in the main event.
