Manchester United's Wayne Rooney slaps WWE superstar at Raw

Wayne Rooney has always had a bit of a temper on him. The fiery former Everton man and current Manchester United star showed it off on Monday night, just not on the pitch.

Rooney was in the crowd for WWE's Monday Night Raw, which took place in Manchester, England. It was there that Rooney had a confrontation with WWE superstar Wade Barrett ... with the footballer coming out on top.

Barrett, who is from England and a fan of Preston North End, called Rooney out during the show, but the tension between the two had actually been building for quite a while. Barrett had called Rooney out on Twitter in February after his dive against Preston North End in the FA Cup.

How about that @WayneRooney dive vs @PNEFC? He won't need to dive when I catch up with him.. #BullHammer #BNB

Here is the dive in the match, which United won 3-1.

Rooney replied.

@WadeBarrett ill get stone cold Steve Austin out of retirement for you. Haha

Before the match between Cesaro and Sheamus, Barrett -- at ringside as an onlooker -- spoke his usual trash, directing it at Rooney.

"You know, Wayne, I would offer to have you step inside this ring so we could fight this out like men," Barrett began. "I would offer, but I would hate for little boy to sit there and watch his own father fail. Because let's face it, he gets to experience that every single time you step foot on the football pitch."

After Cesaro made his way outside the ring during the match and gave Rooney a high-five, Barrett confronted and distracted the wrestler. A short while later, Barrett began yelling at Rooney, pointing a finger in his chest. Then this happened:

Ouch to the smack, and ouch to the words Barrett had for Rooney. Sure, Rooney isn't having a great Premier League season with just two goals in 11 matches, but he is by no means a failure -- on the pitch or in WWE.

Rooney's smack on Barrett provided a distraction that allowed Cesaro to capitalize and win the match.

Rooney 1, Barrett 0.
