#3. Ricochet
WWE's landscape is about to change in a big way, with AEW putting pressure on WWE to reinvent itself, and new Executive Directors Eric Bischoff and Paul Heyman entering the fold to reshape the blue and red brands creatively.
As we reported last week, Paul Heyman is said to be very high on current United States Champion Ricochet, who would make a great WrestleMania opponent for Rey Mysterio.

With Mysterio returning to TV on Raw this week, it is possible the bout between Mysterio and Ricochet could happen sooner rather than later, but given their similar sizes and in-ring styles, WrestleMania could be a great stage for the two high-flyers to showcase their skills in a final bout for Rey Mysterio.
Ricochet has wrestled under a mask before, working as Prince Puma in Lucha Underground, so a possible WrestleMania scenario could see Ricochet retire Rey Mysterio at the big PPV, only for Mysterio to hand down his mask to the rising WWE Raw star.
