Rivalries dominant the world of professional sports - from one-on-one competition to team play; every sport has its share of great rivals. This adds a certain flare to a game/match/contest that we would not necessarily get to feel on any given day.

When the Dallas Cowboys suit up to play the Washington Redskins, the feeling is there. That age-old sense of unspoken hatred that fuels both sides to rise above all expectations and take that gridiron glory away from their opponent.

When the Montreal Canadiens takes to the ice against the Boston Bruins, all cards are placed on the table. The hits seem harder, the shoots seems quicker, and the thirst for blood seems unquenchable.

When the San Francisco Giants take to the field to play a ballgame against the Los Angeles Dodgers, the tension in the air can be sliced with a knife and served to the spectators who came to view the California teams as they do battle on a field of honour.

Rivalries make professional sports that much better. It all comes back to that feeling. That sense of knowing that you are watching something special - something that will live forever in the history books.

Professional wrestling - while predetermined - has also compiled a long list of rivalries. The difference between professional wrestling and any other sport is crystal clear but the luster remains the same. The hope of that big, bright, shining moment.

The following article will take a look back at some of these squared-circle-brutes as they face-off against their greatest foes in the land of violent-make-believe. The feuds that have stood the test of time.

These are the top 20 greatest professional wrestling rivalries of all time:

Twenty years ago, this rivalry would have found a much higher spot on this list. However, we must still recognize the rivalry between Hulk Hogan and Andre The Giant due to its epic implication.

WrestleMania III shattered records and the rematch between Hogan and Andre, which was aired on television, would also break new ground in terms of viewers in America for a professional wrestling event.

Cactus Jack vs. Vader has a certain sound to it; an indefinably ring that may attract psychopaths and the unstable masses - and really, how else can we have a Cactus Jack and Vader feud.

These two men went at it like savages during their time together. In fact, it was due to a match with Vader in Germany and an infamous botched spot that Mick Foley no longer has his entire right ear.
