Hours after Manchester City manager Manuel Pellegrini issued a public apology for questioning the integrity of the referee who oversaw his team's Champions League loss to Barcelona, UEFA charged him with misconduct, AP reported. Pellegrini could face a touch-line ban if he's found guilty after UEFA opened disciplinary proceedings Friday. After City's 2-0 first-leg loss, Pellegrini suggested referee Jonas Eriksson favored Barcelona and was "not impartial." Pellegrini said: "Maybe I said some things I didn't mean, so I apologize for what I said." Barca went in front from a penalty after City defender Martin Demichelis was sent off. Pellegrini says "it is not my way to act to criticize the referee, but in that case it was not a good day and he decided the game." -- SPA 20:34 LOCAL TIME 17:34 GMT تغريد
