There is one storyline in the WWE right now that fans are actively excited about ahead of each match.
They have only actually had one singles match against each other, but Dean Ambrose and Seth Rollins are setting the WWE alight on a weekly basis.
The two have combined to give some of the biggest moments in the WWE this year, from the incredible lumberjack match at SummerSlam, to the shocking scenes on RAW when Rollins curb stomped Ambrose's head through cinder blocks.
It all started the night after Payback in June when, after arguably the biggest victory in their WWE career, the Shield came to an end.
Since the moment Rollins assaulted his former brothers with that steel chair, Ambrose has been out for his blood.
They were scheduled to face off at Battleground but a backstage altercation saw Ambrose removed from the arena and Rollins crowned the winner by forfeit.
The one match they have had is up there with the best of this year and their rivalry is pretty much unchallenged as the best of 2014.
Although they have been after each other for five months now, it doesn't seem like this rivalry will be coming to an end any time soon.
Many years to come?
There are a handful of rivalries throughout WWE history that could be seen as defining generations.
The Rock vs Stone Cold Steve Austin, Hulk Hogan vs Rowdy Roddy Piper and Shawn Michaels vs Bret Hart are amongst the biggest.
In recent years, the biggest rivalry has been John Cena vs Randy Orton and will be reignited once again this Sunday at Hell in a Cell.
Compared to these great rivalries which have all headlined WrestleManias aplenty, Ambrose vs Rollins should be set to be their next one.
The two will not feud continuously for the next few years, but they will always be on each others radar and could arguably be the first great rivalry of the NXT generation.
I personally question just how much further they can take the rivalry between the two but the same questions were raised in each of the other legendary rivalries.
I have no doubt that Rollins vs Ambrose will be a feature in the WWE for many years to come and it will only continue to amuse, baffle and entertain the WWE Universe.
