Who would you rather start v Almeria - Lunin or Kepa? Why?

In light of Thibaut Courtois' season-ending ACL injury, Real Madrid have brought in Kepa Arrizabalaga on a season-long loan from Chelsea.

But Los Blancos still have a backup keeper in Andriy Lunin who kept a clean sheet in the La Liga opener v Bilbao last weekend.

The question is, who would you rather start v Almeria on Saturday? Lunin or Kepa? Why?
