Episode 439: Libertadores semi-final review and superclásico preview

This week Sam and Santi look back on both Copa Libertadores semi-finals, one of which was rather more dramatic and closely fought than the other, and preview Sunday's superclásico at the Bombonera. We also discuss a tightening title race, as Atlético Tucumán have picked up just one point from two games since we last recorded, allowing Gimnasia to go dead level with them at the top of the table.
