“The real problem is most of the sports authorities do not wish to have positive tests”
The shocking discovery found 16 tests showed the players had taken morphine, Ritalin, Triamcinolone and amphetamine.
It is understood eight were from last season, six from 2017/18 and two from 2016/17.
They were reportedly tested by the UK Anti-Doping authority, but the footballers were allowed to play on after the FA agreed the drugs were for medical purposes.
But, fans were kept in the dark and now experts fear the system is open to abuse and that the Prem could face a doping scandal.
Any reputational damage could spook footy chiefs who rake in £4.5billion from a three-year broadcast deal alone.
Labour shadow sports minister Dr Rosena Allin-Khan told The Sunday Mirror: “With such vast amounts of money being generated from the game, it is vital fans who spend their hard-earned money know it is being played fairly.
“A lot of work goes into ensuring drug cheats are stamped out. Authorities should look at publishing these results routinely for transparency.”
Ex-World Anti-Doping Agency (WADA) president Dick Pound said sports bosses did not want to tarnish their reputation.
He told the publication: “For the largest sport in the world which is highly aerobic, the fact there are so few positive outcomes is a matter of suspicion in its own right.
“The real problem is most of the sports authorities do not wish to have positive tests. They think it’s bad for their reputation. They don’t want to invest in any major effort.
“My view when running WADA was that FIFA had little – if any – interest in digging into the problem. That’s what cycling used to say. There’d be another test and they’d say it’s not indicative of widespread usage in cycling.
“Track and field was a bit like that. Weightlifting was a bit like that. Swimming is currently like that. It does take a crisis and then a real uprising to produce some action.”
