BBC Sport's chief sports writer Tom Fordyce said Thiam deserved her win, adding: "Five personal bests across seven events, a woman who is only just getting started and should go on to dominate the heptathlon for years to come."
The Britons had been rooting for Jessica Ennis-Hill to repeat her heptathlon victory at the London Olympics four years ago. However, it was not to be and a great overall performance by Nafi Thiam meant gold for Belgium and Silver for Great Britain.
On their website the BBC writes "For the brilliant 21-year-old this is a well-deserved victory”. "Five personal records in seven disciplines. She has only just started out and will dominate the heptathlon for years to come.”
