Ryanair looking at MS-21’s or C919 as possible 737 replacements?

why would he be looking a a new fleet ? when Ryanair already has probably the youngest fleet of the low cost airlines.
I thought he had a very good deal from Boeing and he tried to get the same deal from Airbus and they told him to do one.
I would of though the cost of training flight crew and cabin crew and ground equip for the new aircraft would not be cost effective.
