Arsene Wenger says that he suspected some of his Arsenal players had been using performance-enhancing drugs before coming to Highbury.
The Arsenal squad regularly undergoes blood tests, and Wenger says that some had abnormally high red blood cell counts – a symptom of using Erythropoietin (EPO).
“We have had some players come to us at Arsenal from other clubs abroad and their red blood cell count has been abnormally high,” said Wenger.
“That kind of thing makes you think.
“Drugs are a problem in all high-level sports. I wouldn’t say they were a big problem in football, but I wouldn’t say that it does not exist.
“There are clubs who dope their players without the players knowing.
“The club might say that they were being injected with vitamins and the player would not necessarily know that it was something different.”
