【明報專訊】YESTERDAY morning Barcelona (Barca) beat Manchester United (United) 2:0, winning its UEFA Championships League title and achieving the Treble. (It has also won the La Liga and Copa del Rey in the same season). This year it has achieved more than any other European team. Its members display consummate skill, they play like one, and their passes are seamless. They have fully demonstrated what is most enjoyable about football. One may say Barca's success should no longer be measured by the number of titles it has won. It has redefined "elegant football". It is certainly thanks to the importance FC Barcelona attaches to its youth system that it has achieved such wonders.
