For high balls, sure. But I sincerely doubt that is going to be a deciding factor on who plays pivot. I doubt it would even be a consideration. What a player helps us achieve when we have the ball is far more important than whether They are out jumped once or 2ice in the middle during the course of a game. Besides it is not winning the a jump ball that concerns Pep ( at least if we believe his interviews.) Rather its how well we win the 2nd ball. I.e how often we win possession after an air duel. If we are winning 70% of 2nd balls in midfield, its irrelevant who's head got to the ball first in the jump itself. On the other hand defending headers in the box or around it seem to be more of a concern of his if the links to the likely fullbacks are true. Heinrich is 6 feet tall and Berciche is 5"11. Not that I think their heights are particularly determinative of interest either. I think their style and talent on the ball is more indicative So no, I don't think Carhvahlo or Nzonzi are better fits because of their heights. They 'll have to in fact be better footballers both technically and tactically, and I'm certain Nzonzi isn't. Cahvahlo I have yet to see the hype outside of his YouTube videos. Isco and Silva are just better players than the aforementioned. As for Garcia, it will come down to Pep's faith or believe. Talent and comfort wise he looks every bit the part.
