After Rey Mysterio's shock return at the Royal Rumble on January 28, fans have been wondering if they're going to see him regularly back in a WWE ring again soon. The former WWE World Heavyweight Champion entered the 30-man rumble at spot number 27, receiving one of the biggest ovations of the night.He managed to eliminate Adam Cole, deliver a double 619 to Roman Reigns and John Cena, but was ultimately thrown over the ropes by Finn Balor.Since that night, he's not appeared on tv or at any WWE event, leading to fans questioning if he came back for one night only. But if WWE's latest Fantasy Warfare teaser is anything to go by, we could see Mysterio set foot inside the ring for at least one more dream match. Earlier today, WWE posted a video on their Twitter feed, asking fans how fast they would buy tickets to see Mysterio take on none other than current WWE Champion AJ Styles. The video shows clips of both men cutting some of their best promos and has been edited cleverly to make it sound like they're talking to one another in the same ring. The teaser ends with an old style Smackdown graphic, previewing a match-up between Styles and Mysterio, one that's no doubt going to get fans hyped. 

It took Mysterio just a few hours to respond to the potential dream match and he took to Twitter to reveal what he would say if Styles did indeed call him out to make the match. 

"Can’t answer on how fast to buy the tickets, but what I can answer is on how fast would I accept....Right Away," he said, quote tweeting the WWE video. 

Unsurprisingly, his tweet went down very well with fans on Twitter, who are demanding that the match is made. 

However, there has been no response from Styles.

And with the WWE Champion preparing to defend his title in a fatal 5-way match at Fastline on March 11, he can't be blamed for having no time to concentrate on Mysterio. 

That match was originally made as a triple threat between Styles, Kevin Owens and Sami Zayn, but Baron Corbin and Dolph Ziggler were added after wins on Smackdown Live earlier this week. 

The fatal 5-way will perhaps be the toughest challenge Styles has ever faced as a champion, but if he wants another Wrestlemania moment, he's going to have to get through it. 

And if he does, maybe then he'll have time to think about putting on a dream match with Mysterio.
