Davis Cup Tennis : GB v Argentina

Sue Barker introduces live coverage of the concluding day’s singles matches in the Davis Cup semi-final between Great Britain and Argentina in Glasgow.
The British team are vying to reach back-to-back finals, having won the competition for the first time in 79 years in 2015. Argentina await their first title but have been runners-up three times in the last 10 years and reached 11 semi-finals out of the last 15.
Sunday’s action could see local hero and three-time Grand Slam champion Andy Murray take on former world number four Juan Martin del Potro in a repeat of their epic Olympic Games final in Rio, which Murray won in four sets after more than four hours’ play.
The winners of the tie will face either Croatia or France in the final in November.
