Dr Mark Bonar bragged to undercover reporters that he prescribed banned substances to a string of top Brit athletes.
Dr Bonar claimed his former patients included Arsenal, Chelsea, Leicester City and Birmingham City stars.
Yesterday ex England striker Stan Collymore, 45, urged all players to take a test to prove the sport is clean.
He tweeted: “Every Premier League player should volunteer blood, hair samples and urine.” Former
England Under-19 star Leon Knight, 33, said: “This doping scandal is mad.’’
Last month we revealed how Knight and fellow former young England star Curtis Woodhouse, 35, said clubs tried to protect players by tipping them off to dope tests.
Yesterday all four clubs named in the Sunday newspaper scoop hit back. A spokesman for Chelsea said: “Chelsea Football Club has never used the services of Dr Bonar.”
An Arsenal spokesman said the report contained “false claims which are without foundation”.
Culture, Media and Sport Secretary John Whittingdale said: “Sports fans are entitled to be sure that what they are watching is true and fair with all athletes competing on a level playing field. If it becomes clear that stronger criminal sanctions are needed then we will not hesitate to act.’’
He called for an investigation into watchdog UK Anti-Doping which was allegedly given “evidence” the doctor had prescribed banned drugs two years ago.
Dr Bonar was sacked by the private Omniya Clinic in London on Friday after bosses discovered he did not have a licence to practice medicine in the UK.
Dr Bonar was unavailable for comment but reportedly insisted he had not breached GMC rules.
