Luis Enrique, Pep Guardiola, Xavi, and Mikel Arteta have two things in common. They are four of the last remaining eight coaches in the UEFA Champions League. They’re also all former FC Barcelona academy players.
Luis Enrique, Guardiola, and Xavi all played for Barcelona’s first team. In fact, all three appeared in matches together.
Arteta played for Barcelona B after coming through the youth academy, but he never played for the first team. However, he could not break into the team, partly because they already had the three others previously mentioned.
He played for many clubs in his career, most notably Everton and Arsenal, but he never got a Spanish national team call-up beyond senior level.
