Barcelona were made to work hard against fourth-tier opponents as they booked their place in the last 16 of the Copa del Rey on Sunday with a 3-2 win at Barbastro courtesy of goals from Fermin Lopez, Raphinha, and Robert Lewandowski. Lopez opened the scoring for the visitors in the 18th minute with a tap-in from a low cross from Raphinha, who then made it 2-0, collecting a fine long ball from young debutant Hector Fort in the 51st minute.
