As 16-year-old Marc Jurado looks forward to his future at Manchester United, Barcelona are left wondering how another young talent got away. This is a story as old as Cesc Fabregas' move to Arsenal in 2003.
It hurts the club to see those nurtured in La Masia thrive elsewhere, Jurado had been nine years at Barcelona before deciding to move to Manchester.
These deals hit them financially too if the departed talent then moves for big money. Fabregas was the worst example – not only did Arsenal get the best out of him, and then make money from his sale; but Barcelona were the club buying him when they decided to cash in.
