Argentina v Great Britain. Live coverage of the crucial doubles rubber at the Estadio Parque Roca in Buenos Aires. These two nations have not met in the Davis Cup since 1989 when Argentina triumphed on the grass at Eastbourne. With a partisan crowd and playing on a clay surface, Argentina will be favourites to extend their head-to-head record over Great Britain to 3-1. But doubles specialist Jamie Murray is likely to feature in today's match - possibly with brother Andy - and he is yet to be beaten in Davis Cup doubles.
