Less than a minute after replacing Ivan Rakitic during a strangely discordant el clásico, Andrés Iniesta had Barcelona humming sweeter harmonies again. His first act was to float to the centre, collect from Gerard Piqué and exchange a wall-pass with Lionel Messi – bam, bam, bam – which started a 31-pass move. His next was to set up Neymar for a chance he smashed over. Later he steered a glorious eye of the needle ball that Messi, with the match at his feet, screwed wide.
