Behind every footballing tough guy there lurks a mincing aesthete with a love of art for art's sake, football for football's sake. A win without art is somehow less than a victory; less, almost, than a beautiful defeat. In football, the romantic and the pragmatist are ever at war in the same breast. Beauty, it must be understood here, is not Barcelona's aim but their method. And last night they were ready to use this method at every opportunity - quick-fire passing of wit and purpose in the danger areas, seeking always to produce an unlooked-for player in a position of threat.
