Surprisingly, one of the most over superstars in the WWE today in Rusev doesn't yet have a match for this year's WrestleMania 34 in New Orleans. The man himself is doing everything he can to change that, and he's already had a few offers.The Bulgarian Brute recently posted out on Twitter that he wants a celebrity to challenge him to a match at this year's Showcase of the Immortals in April. He's already had quite a few responses to his open challenge.Stephen Amell, who wrestled at SummerSlam 2015, replied to his fans by stating that he was too scared of Rusev to fight. The Rock, on the other hand, put Kevin Hart's name forward, but the former United States Champion declined.Now, two celebrities have accepted Rusev's challenge and are willing to step into a WWE ring with him at WrestleMania 34. Those celebrities are Home Alone's Macaulay Culkin, who has wrestling experience, and the other is Skylar Astin, who starred alongside Lana in Pitch Perfect.However, unfortunately for both of these celebrities, their pleas to have a match at WrestleMania have been declined by The Bulgarian Brute for different reasons.Rusev refuses to wrestle Culkin as he 'cannot Hit Little Kevin McAllister or Richie Rich!' This prompted the Home Alone star to respond back and say: "It's cool. I'd be doing all the hitting anyway. #youjustgotculked."

As for Astin, The Bulgarian Brute responded by saying: "Ha! @WWEDramaKing can outsing you! @LanaWWE can outdance you and i .... well i can MACHKA.... Happy #RusevDay."

Unfortunately for Rusev, despite his current popularity amongst the WWE Universe, he's unlikely to be given a match against a celebrity at this year's Showcase of the Immortals. With only weeks left to go until WrestleMania 34 though, it's odd that he hasn't been booked for a match when you take into account how over Rusev Day is at the moment. 

In fact, his involvement on the show may be limited to the Andre The Giant Memorial Battle Royal if it's confirmed for this year. He should be one of the favourites to win that match if it takes place. Still, a match against a celebrity provides an interesting concept for WWE should they wish to explore it.
