While he won't be returning to WWE TV until January 20, Batista has already upset some people backstage with comments he made on Twitter.

After Alberto Del Rio beat Sin Cara on RAW, he said he was entering the Royal Rumble and cut a promo on Batista. Batista then replied on Twitter: "Who is Alberto Del Rio?"

Del Rio wrote back: "I'm the one wining all the major titles while u were getting ur ass kick by your plumber (Vince lucero) See u at the rumble."

Vince Lucero was the fighter Batista defeated in October 2012 in his first and only MMA fight.

Batista then added: "Seems 2 me that some C level stars in a B level star era have bought into their own hype. Don't turn a work into a shoot. #realitycheck"

That tweet was later deleted yesterday, but wrestlers in the company say he buried the entire locker room in one post. One person compared the comment to Triple H once saying that The Undertaker was the only person worthy of wrestling him in the entire locker room. Batista is already returning to the company and walking into a main event match at Wrestlemania, so there are already some disgruntled wrestlers in the back anyway. The comments didn't help his standing.

Batista will be back on the episode of RAW from Dayton, Ohio. He is believed to have signed a multi-year deal (two years) with the company.
