Barcelona have announced the appointment of Sergi Barjuan as interim manager following the sack of Ronald Koeman as first team coach. The 58-year-old Dutchman was dismissed after a 1-0 defeat by Rayo Vallecano on Wednesday night with the Spanish giants sitting ninth in La Liga. Barjuan was before now the coach of Barca B. He will remain in the position of interim manager until the Spanish club hires a full-time manager to replace Koeman.
