The Sevens World Series reaches its climax with the eighth and final leg from Murrayfield. Edinburgh is hosting the event for the first time, with a three-way tussle for the overall title expected between defending champions Fiji, six-time winners New Zealand, and Samoa. All have won tournaments this season and each boast prolific try-scorers in the shape of Fijian William Ryder, Nigel Hunt of New Zealand and Samoa's Mikaele Pesamino. Fiji and New Zealand are seeded to meet in the semi-finals, with the winners likely to meet Samoa or South Africa in the final. England will be hoping to gatecrash the latter stages as the leading European side. John Inverdale presents.
