If WWE World Heavyweight Champion Brock Lesnar opts to return to the UFC following his current WWE run, he has at least one fighter clamoring to be his opponent.

UFC Heavyweight Brendan Schaub said he wants a fight with "The Beast" if he makes his return to the Octagon once his WWE contract is up and he said that he would send Lesnar "back to fake wrestling" if they crossed paths.

"Listen, doing fake wrestling is not the same as being in the UFC," Schaub said on the Jason Ellis Show, according to MMAJunkie.com. "You're playing grab-a--. You know if you're going to win or lose. Yeah, it's hard on your body. Great. He hasn't been competing and training like I have. If he comes back to the UFC, I would 100 percent send him packing back to the fake wrestling."

4 Possible Matches For WrestleMania 31

Lesnar, who was booked to end The Streak of The Undertaker last year at WrestleMania and dominated John Cena at SummerSlam in August to win the WWE World Heavyweight Championship, has been rumored to have some interest in returning to UFC.

Lesnar is likely to drop the title at WrestleMania 31 on March 29 at Levi's Stadium in California and his contract expires the next day. Schaub thinks Lesnar is athletic, but isn't threatened by him.

"I think what he does, he'll still be very successful," Schaub said. "He's so damn big and a very talented wrestler. There's just not that many big, explosive guys who are athletic like he is. So, he's always going to be successful. [But] I don't think [he's going to beat me]."

There have been reports that the WWE, UFC and Bellator MMA may be in a three-way bidding war over Lesnar's services once his current part-time pact with the WWE is up.

Lesnar is a former UFC Heavyweight Champion, but he had to retire from the sport in 2011 due to a bout with diverticulitis.

If Lesnar in fact does re-sign with UFC -- which president Dana White said he is open to -- Schaub will be waiting for him.

"If you're Brock Lesnar, why come to the UFC when you can fake it in the WWE?" he said. [If he comes back], sign me up, man."

While his future is uncertain, Lesnar's next battle is clear as he will take on John Cena and Seth Rollins in a Triple Threat Match at the WWE Royal Rumble on Jan. 25 at the Wells Fargo Center in Philadelphia.
