Talks have stalled between former WWE Champion Alberto Del Rio and Lucha Underground, sparking rumours of a return to WWE. Del Rio - known as Alberto El Patron in the California-based promotion - made several televised appearances earlier this year, even competing for the Lucha Underground Championship. However, negotiations seem to have broken down between the two parties, reportedly regarding money and future creative decisions. A source close to Del Rio has even suggested that he is "out as of right now", a mindset which surely opens the door for a future WWE return. According to the Wrestling Observer Newsletter (by way of WrestleZone.com), the 38 year old has told friends he'd want to be back with WWE in time for WrestleMania 32. With that in mind, excited fans should rule out an immediate return; he's also spoken of his desire to take time off in December, intending to spend more time with his family. Del Rio, a former WWE Champion, World Heavyweight Champion, and Royal Rumble winner, seemed to be enjoying a good level of success during his initial spell with WWE - but was released in 2014 after an incident with a backstage employee, who is thought to have made a racist joke. Should Del Rio become available, it's likely that WWE would be keen to snap him up. Their desire for a top Hispanic star has been particularly well-documented recently; difficulties reportedly arose with promotors of the recent Mexico tour, who were angry at WWE's failure to provide a big Latino draw. Del Rio certainly has the credentials to fulfil such a role.
