It’s unknown whether or not the two sides have been in talks, but there is definitely interest in Del Rio on WWE’s part, and the company has been discussing ways of using him on TV.
Going further, Wrestlezone pointed out that this would fulfill the WWE’s need for a great Hispanic superstar. That could stand true given the recent rumors of a possible return for Carlito. In terms of Del Rio’s desire to return, that comes with some caveats according to an early September report in the Wrestling Observer newsletter.
In regards to Rey Mysterio and Alberto Del Rio returning to WWE in the future, the mentality right now is they aren’t looking to come back to the company. They would however consider it if a reduced scheduled was put on the table because they are doing very well right now working whenever they want to.
The WWE and Del Rio parted ways back in August 2014 when, according to reports, Del Rio slapped a web producer for making a racist comment.
Since then, the Mexican Aristocrat has made appearances in Ring of Honor, Lucha Underground and AAA’s Triplemania.
