Anne Keothavong made the most of her lucky loser spot to reach the second round of the Luxembourg Open with victory over Kiki Bertens yesterday.

The rivalry with Roger Federer which helped to propel Andy Murray into his greatest summer will resume here today when they face each other for the first time since their gold-medal match at the Olympic Games. The Swiss and the Scot meet in the semi-finals of the Shanghai Masters, where Murray has yet to lose a match, having won the tournament in his two previous appearances.
