The only reason why this selection is so low in the list is that it is pretty clear at the moment that Daniel Bryan and Sami Zayn are on a collision course. It would be very weird to tease a clash between Sami Zayn and Daniel Bryan and have Roman Reigns step into the fray.Never content. If there’s more, I’ll take it. https://t.co/Nc2wFUmYQs— Roman Reigns (@WWERomanReigns) November 19, 2020That said, undoubtedly and undisputedly, Roman Reigns vs. Daniel Bryan is a money feud and there is actually a story in place for it as well, especially if you consider that Jey Uso and Daniel Bryan had a recent clash, where Roman Reigns was an integral part.Plus, Daniel Bryan just cannot have a bad match and despite how many matches he loses, he is still one of the most revered men on the WWE roster.Also, this goes without saying, but the match quality will be impeccable indeed.
