Eric should under no circumstances start for Barcelona when Araujo is available.
When Chelsea and Real Madrid can win CL titles by having Rudiger and Varane in defence, both whom aren't great on the ball then Barcelona SHOULD win games with Araujo there.
Araujo is a very good defender. Eric Garcia is not. Maybe I'm too harsh on Eric, but I don't see any outstanding qualities that makes him stand out like Pique did when he was young and joined us.
I predict he'll end up leaving within the next couple of years. He cannot cope with modern day forwards at an elite level. Doesn't have the pace nor size/physicality to compete. Need at least one.
