#4 Aleister Black vs 'Demon' Finn Balor
Aleister Black suffered a legitimate injury a few weeks prior to NXT Takeover: Brooklyn. He was written off television with a mysterious assault at the hands of an unknown assailant in a parking lot.
Black has done everything in NXT, and his main roster promotion is long overdue. I expect him to exact revenge on his assailant and jump ship to the main roster as a surprise entry in the Royal Rumble match next year.
Finn Balor has been lost as a babyface on the main roster, and has been embroiled in a lacklustre feud with Baron Corbin for over 3 months now. Balor's sorrowful place in Raw's hierarchy is disturbing to watch, however a feud with Aleister Black, and a heel turn could be all that he needs to revitalise himself.
A feud with Black could be the catalyst for a heel turn for 'The Demon King'. This feud is only fit for a grand stage such as WrestleMania, and it could happen as soon as next year. The entrances alone would be a magnificent sight to behold.
