#3 Bayley
Everyone loves an underdog and there are few superstars in the WWE today who fit that bill quite like Bayley. The former Women's champion has had a rough ride over the last 12 months and if her booking in the Royal Rumble is anything to go by, it doesn't look as if that is going to change anytime soon.
Bayley's popularity is undeniable, however, and if the WWE decided to pull the trigger on her, she could be the perfect candidate to finally overcome Asuka. Most fans would rather see Asuka's streak end clean, as previous examples of heels ending streaks (Kevin Nash, I'm looking at you) often make the victory feel tainted and can somewhat tarnish the reputation of the streak itself, so Bayley picking up the 1-2-3 could be the perfect end to one of the most memorable runs in WWE history.
Building Bayley as the plucky underdog who finally overcomes the unstoppable force would make for excellent television and would make Bayley one of the biggest babyfaces in the company, which is exactly what she should be.
