The UK Anti-Doping watchdog (Ukad) has said it is "deeply concerned and shocked" by the claims a British doctor has doped sports stars.
The Sunday Times reported that Dr Mark Bonar had been secretly filmed discussing prescribing banned performance-enhancing drugs to the "elite" sports professionals.
Ukad chief executive, Nicole Sapstead, confirmed the publicly-funded body had received allegations involving Dr Bonar in April and May 2014 during interviews with an unnamed sportsman.
Following those interviews and an investigation, UKAD found that there was nothing to indicate that Dr Bonar was governed by a sport and UKAD had no other intelligence to corroborate the sportsman's allegations.
Chairman David Kenworthy said an independent review of the allegations against it would be conducted "as soon as possible", to examine the information passed to them in 2014 and to discern if the proper procedures were followed.
"Ukad is a publicly funded body and it is correct that it be held to account for any actions it takes. That accountability rests with the independent board," he added.
Leicester, Arsenal and Chelsea have expressed their disappointment at the doping allegations they claim are "without foundation".
An inquiry has been ordered into the anti-doping watchdog over its handling of doping allegations involving a British doctor.
