Mayor of London Sadiq Khan has once again expressed his desire for London to host WrestleMania, making a plea to Triple H while speaking to CNBC:
“I’d love for WrestleMania to come to London, Triple H if you’re watching, we want WrestleMania to come to London.”
“If WrestleMania came to London, my message to the team there is that we wouldn’t just have a great weekend, we’d have a festival, of you know, legends in WrestleMania coming to London, current stars, but also future stars as a well, it will open a completely new market for them as well.
“I think the potential has not been reached in terms of WrestleMania. We are the sporting capital in my view, of the world. And WrestleMania wants to expand, the obvious place to come is London.”

WrestleMania should go to Mexico (the only North American country of the big 3 that has never had a WrestleMania) and take place at the Estadio Azteca stafium, located in Mexico City which has a capacity of 87,000 spectators.
Likewise a TripleMania PLE should come to Canada the only North American country it hasn’t been held in as AAA’s TripleMania was been held in USA in May 11, 1996 for Triplemanía IV-A.
