Pique didn't have a particularly good season, that's true, but I still think he fits the scheme of things well at Barca. He does better with someone like Abidal in the team. That being said, other than Alves, Xavi, Iniesta, Villa and Messi, nobody's beyond being benched in the team in light of players who deserve a chance. Pep gave opportunities to versatile defenders like Fontas, Adriano and Enrique to assess the team's depth. That has always been his style usually in non critical matches.
"O people, we created you from the same male and female, and rendered you distinct peoples and tribes, that you may recognize one another. The best among you in the sight of GOD is the most righteous. GOD is Omniscient, Cognizant." (49:13)
