Everyone has to fight for their spot. It's not like Pep are gonna handout starting eleven spots like it's a charity just because they're from the academy. The eleven most capable of winning the match starts, if it is Adarabioyo, Garcia, Otamendi, Stones or Todibo doesn't matter. I think Todibo has a better chance than Garcia of being a success right away given his physicality, speed and experience playing at the highest level. Tobido really looks like a Pep CB with the physicality required to be an outstanding CB in the premier league. He's one of the hottest CB prospects in the world and is probably available for a cut price due to Barcelona's finances.
There is no secret that we're in for at least one center half in the summer, and we should definitely make it count given the performances this season. That said I really rate Garcia and THB highly, but a player should only play if they deserve it and are the best option
