#1 To turn her face organically
A major predicament that WWE Creative is facing in possibly building a Sasha Banks vs Bayley feud is that both women are heels at the moment.
As pointed out by my friend and Sportskeeda's own Riju Dasgupta in one of his articles, either Superstar turning on the other does not establish a clear babyface. So the best way forward is to allow Sasha Banks to tough it out in the ring and win the crowd over with her performances and passionate promos.
Banks won't get a better opportunity than Money in the Bank for the same. She can overcome multiple setbacks during the match to eventually land the briefcase.
We've already seen how current WWE Champion Drew McIntyre became a fan-favorite after eliminating Brock Lesnar during this year's Men's Royal Rumble Match before going on to win the whole thing.
The Legit Boss also needs a few similar moments to endear herself to the crowd. And once she has been established as the clear babyface, with the Money in the Bank briefcase in her hand, Sasha Banks would have a clear pathway for starting another feud with Bayley.
