Barcelona played with several youngsters but still managed to turn on style and thrash Athletic Bilbao 4-1 on Saturday to go three points clear at the top of the Primera Liga. Bojan Krkic, who replaced Zlatan Ibrahimovic in Barca's starting line-up after the Swedish striker picked up an injury in the warm up, scored twice to steal the show at the Nou Camp. Jeffren, 22, and World Player of the Year Lionel Messi were also on the scoresheet to give Barcelona a comprehensive win. Markel Susaeta scored a consolation for Bilbao with 13 minutes remaining. Barcelona, who chase a second successive league title, are on top of the table with 77 points. Their arch-rivals Real Madrid can go level on points with them if they beat Racing Santander on Sunday. Barcelona will meet English side Arsenal in the second leg of the Champions League quarter final on Tuesday at Emirates Stadium. The first leg ended in a 2-2 draw. The Catalans will then face Real in a top-of-the-table clash at Santiago Bernabeu next Saturday. Barcelona 4-1 Athletic Bilbao
