Andrew Castle is in Liverpool to host live coverage of the third and final day of Britain's Davis Cup tie against Poland.

Today's schedule features the reverse singles, in which Britain will be relying on Andy Murray, assuming the Scot is fit enough to play. Murray has won his last eight singles rubbers in the competition but didn't take part in Britain's defeat to the Ukraine earlier this year due to a virus.

Greg Rusedski joins Andrew in the commentary box. Show less
