#1. Tommaso Ciampa and Johnny Gargano
Even though there were reports that this was going to happen ahead of last year's NXT Takeover: Chicago, many fans were still let heartbroken when DIY failed to win back their Tag Team Championships from The Authors of Pain and Tommaso Ciampa then decided it was Johnny Gargano's fault.
The box was already on the screen, many thought that the pay-per-view had come to an end before Ciampa threw Gargano into the screen and then began a beatdown that has been replayed in Gargano's head hundreds of times over the past year.
Ciampa was forced to miss almost a year of action following this turn when it was revealed that he had suffered a knee injury that required surgery, but since his return in Philadelphia back in January, these two former friends have ensured that there are no pieces of their friendship that are left to fit back together with some of the most brutal matches in NXT history.
