British sprinter Adam Gelili has tweeted about his team being disqualified from the 4x100m relay at the World Athletic Championships in Moscow today:
Thank you all for the messages of encouragement. To be so close to receieving a medal and have it taken away is heartbreaking
As a team we will pick ourselves up and carry on until we get it right. Onwards and upwards!
BIg up to the GB 4x100m women on receiving the news for bronze. Extremely proud! Just a shame they don't get their moment on the podium
Mo Farah is hailed as Britain's greatest ever athlete after repeating his Olympic success with a double victory at the World Championships.
He won two Olympic gold medals last year and has already won gold this year in the 10,000 metres but is he the greatest of all time?
