Luis Enrique's departure brings uncertainty to Barcelona (The Associated Press)

Although the coach had been under pressure and many expected him to be replaced next season, few anticipated he would reveal his intention to leave with three months left and with the team still contending for titles. The announcement - on the night Barcelona regained the lead in the Spanish league - quickly turned the focus away from team's recent successes on the field and brought attention to its uncertain future.
